Stainless Steel " L" "H" Grade By yaang.com

Austenitic stainless steel grades are those alloys which are commonly in use for stainless steel applications. The austenitic stainless steel grades are notmagnetic. The most common austenitic alloys are iron-chromium-nickel steel and are widely known as the 300 series. The austenitic stainless steel pipe, because of their high chromium and nickel content, are the most corrosion resistant of the stainless steel group providing unusually fine mechanical properties. They cannot be hardened by heat treatment, but can be hardened significantly by cold-working. Straight Grades

Selection of Stainless Steel for Water Tank Application By yaang.com

Stainless steel grades, such as the 304 (1.4301) or 316 (1.4401) types are generally suitable for storing and handling cold or unheated drinking town's waters. Localised corrosion by crevice or pitting mechanisms is not usually a hazard in properly designed, fabricated and finished tanks handling clean waters of drinking quality.

Stainless Steel Section for Structural Application By yaang.com

Unlike carbon steel, there have not been listings of open section sizes for stainless steel structural sections, until Sections Directory in May 2004. This gives the full range of 'standard' stainless steel sections that are readily available and the companies who supply them. The directory distinguishes between producers and distributors as well as showing the main stainless steel grades available from each supplier across the complete size range.

Fire Resistance Rating and Testing of Stainless Steel By yaang.com

The inherent oxidation resistance and elevated temperature strength of stainless steel finds useful application in buildings and structures where fire resistance is very important. The most useful family of stainless steel for these applications is theaustenitic, but the short-term nature of fire means that embrittlement should not be practical issue and so the ferritic andduplex families can also be considered.

How the Austenite Ferrite Balance Achieved By yaang.com

To understand how duplex stainless steel works, first compare the composition of two familiar steel austenitic 304 (1.4301) and ferritic 430 (1.4016).

Structure	Grade	EN Number	C	Si	Mn	P	S	N	Cr	Ni	Mo
Ferritic	430	1.4016	0.08	1.00	1.00	0.040	0.015	-	16.0/18.0	-	-
Austenitic	304	1.4301	0.07	1.00	2.00	0.045	0.015	0.11	17.5/19.5	8.0/10.5	-

The important elements in stainless steel can be classified into ferritisers and austenitisers. Each element favours one structure or the other:

Austenitic Stainless Steel Grades Comparison Table By yaang.com

Austenitic Stainless Steel Grades Comparison Table is intended to relate former BS, EN, German and Swedish grade designations to the current EN steel numbers, AISI stainless steel grades and UNS numbers. The table is based on the 'wrought' ie long products (stainless steel bars etc), flat products (stainless steel plates etc) steel numbers published in EN 10088 and related standards.
Casting products use different composition and so have their own steel numbers in EN 10283. The related castings grades in both EN 10283 and BS 3100 are included in the table.

Austenitic Stainless Steel By yaang.com

This type of stainless steel is dominant in the market. The group includes the very common AISI 304 and AISI 316 steel, but also the higher alloyed AISI 310S and ASTM N08904.

Austenitic stainless steels is characterised by their high content of austenite-formers, especially nickel. They are also alloyed with chromium, molybdenum and sometimes with copper, titanium, niobium and nitrogen. Alloying with nitrogen raises the yield strength of the steels.
