Stainless steel is defined as iron alloys with a minimum of 10.5% chromium. Other alloying elements are added to enhance their structure and properties, but fundamentally, stainless steel tubes are considered for selection as steels with corrosion resistant properties.

Cleaning of Stainless Steel Tubes By yaang.com

The final operation of stainless steel tubes fter fabrication or heat treatment is cleaning to remove surface contamination and restore corrosion resistance of the exposed surfaces. Degreasing to remove cutting oils, grease, crayon markings, fingerprints, dirt, grime and other organic residues is the first step. 

Properties at Cryogenic Temperatures of Stainless Steel Tubes By yaang.com

The austenitic stainless steel tubes remain tough and ductile to very low temperatures. Metals such as iron and constructional steel undergo a marked decrease in ductility at lower temperature.

Common Cryogenic Temperatures:

Corrosion Resistance of Stainless Steel Tubes By yaang.com

Carbon steel suffer from 'general' corrosion, where large areas of the surface are affected. Stainless steel tubes in the passive state are normally protected against this form of attack, however, localised forms of attack can occur and result in corrosionproblems.

The assessment of corrosion resistance in any particular environment, therefore, usually involves a consideration of specificcorrosion mechanisms.
These mechanisms are principally:

Intergranular Corrosion of Stainless Steel Tubes By yaang.com

When austenitic stainless steel tubes are heated or cooled through the temperature range 425-900C (800-1650F), chromium tends to combine with carbon to form chromium carbides. The carbides precipitate preferen- tially at grain boundaries depleting chromium from the adjacent areas. This reduces the corrosion resistance of the chromium depleted areas, sensitizing the alloy to Intergranular Attack (IGA).

Preparing Metallographic Stainless Steel Specimens By yaang.com

The surface of a metallographic stainless steel tubes are prepared by polishing, grinding,and etching. After preparation, it is often analyzed using optical or electron microscopy. Using only metallographic techniques, a skilled technician can identify stainless steel material properties.
Mechanical preparation is the most common preparation method. In a series of steps, successively finer abrasive particles are used to remove material from the sample surface until the desired surface quality is achieved. Many different machines are available for doing this grinding and polishing, able to meet different demands for quality, capacity, and reproducibility.

ASTM A789 Seamless Welded Stainless Steel Tube By yaang.com

ASTM A789 covers standard requirements for grades of nominal wall thickness, stainless steel tubes for services requiring general corrosion resistance, with particular emphasis on resistance to stress corrosion cracking. These steels are susceptible to embrittlement if used for prolonged periods at elevated temperatures. Heat and product analyses shall be performed wherein the steel shall conform to the required chemical composition for carbon, manganese, phosphorus, sulfur, silicon, nickel, chromium, molybdenum, nitrogen, copper, and others. All stainless steel tubes shall be furnished in the heat-treated condition in accordance with the specified temperature and quenching conditions.

Nickel Alloys Pipes and Tubes By yaang.com

Nickel alloy tube is one of yaang Stainless Steel specialties. The addition of nickel adds unique characteristics to those alloys in which it comprises a large percentage of the element makeup. Normally, nickel content is limited to 8-11% in most 300 series stainless steels, but in the alloys below it represents a much larger percentage of the components in each respective alloy. Each of the high nickel alloys described below has unique characteristics which should be considered prior to purchase. Tube Technology can form tubing in these alloys to sizes and tolerances within our manufacturable range. All of our nickel alloy tube is seamless and cold drawn/rolling to size, and finished in bright annealing. custom manufactured to your specifications, and can be manufactured in tube lengths up to 60’.

Martensitic and precipitation hardening stainless steel grades by yaang.com

Martensitic and precipitation hardening stainless steels are heat treatable and can therefore provide hardness and strength in a wide range. Allowing to workability they are supplied in solution annealed condition. The downstream manufacturer performs final heat treatment to meet the mechanical properties required.

Martensitic grades are basically Fe-Cr alloys with a higher carbon content than ferritics which enables them to harden on cooling in air, oil or water. Depending on grade and intended use, ductility is improved by tempering.

Type 347 Stainless Steel is a chromium nickel stainless steel which has been modified by the addition of columbium and tantalum. The main advantage of this is an excellent resistance to intergranular corrosion which is common to other austenitic stainless steels following exposure to temperatures of 800° to 1500°F. Type 347 Stainless Steel has about the same general corrosion resistance as Type 302.

UNS S34700 347 Stainless Steel Pipes, Flanges, Pipe Fittings By yaang.com

347 Stainless Steel Detailed Description

Type 347 stainless steel is a stabilized austenitic stainless steel similar to type 304 with an addition of Columbium and Tantalum. The columbium serves to produce a stabilized type of stainless steel which is immune to chromium carbide precipitation. This type of grades are thus recommended for parts fabricated by welding which cannot be susequently annealed or for parts which must operate in service between 800 – 1600°F.

Stainless Steel 347 (UNS S34700) By yaang.com

Type 347 stainless steel has slightly improved corrosion resistance over type 321 stainless steel in strongly oxidizing environments. Type 347 stainless steel is stabilized with columbium, it is preferable for aqueous and low temperature environments due to its good resistance to intergranular attack. Both 347 stainless steel and 321 stainless steel offer good resistance to polythionic acid stress corrosion cracking, encountered in oil refineries. The high temperature oxidation resistance of 347 stainless steel is similar to that of 304 stainless steel. Useful to 1500°F.

Stainless Steel 904L UNS N08904 WNR 1.4539 By yaang.com

UNS NO8904, commonly known as stainless steel 904L, is a low carbon high alloy austenitic stainless steel which is widely used in applications where the corrosion properties of AISI stainless steel 316L and AISI stainless steel 317L are not adequate.

About 321 Stainless Steel Information By yaang.com

321 Stainless Steel is a standard austenitic 18/8 stainless steel grade, (304), but stabilized by Titanium. The titanium within means the stainless steel is intergranular corrosion resistant after heating, (between 425-900 degrees Celsius). Remarkably high strength as well as scaling resistance and phase stability set 321 Stainless Steel apart from other similar grades. This grade is not, however, recommended for welding consumable, as the titanium component does not allow good transfer of heat across a high temperature arc.

Type 321 Stainless Steel is a chromium-nickel stainless steel and with the addition of titanium, type 321 Stainless Steel is resistant to intergranular corrosion. Type 321 Stainless Steel's general corrosion is less than Type 302Stainless Steel.  Type 321 Stainless Steel is used where resistance to intergranular corrosion is required and where the parts are subjected to sustained heating or cooling within the range of 800 to 1500ºF. Type 321 Stainless Steel is commonly used in applications such as exhaust stacks, manifolds and ring collectors.

(UNS S32100) 321 Stainless Steel By yaang.com

321 stainless steel, also known as UNS S32100 and Grade 321, is primarily comprised of 17% to 19% chromium, 12% nickel, .25% to 1% silicon, 2% maximum manganese, traces of phosphorus and sulfur, 5 x (c + n) .70% titanium, with the balance being iron. With regards to corrosion resistance, 321 Stainless Steel is equivalent to Grade 304 in the annealed condition and is superior if the application involves service in the 797° to 1652° F range. 321 Stainless Steel combines high strength, resistance to scaling and phase stability with resistance to subsequent aqueous corrosion.
