Corrosion Resistance of Stainless Steelsto compare stainless steel grades resistance against pitting. The higher the number the betterthe resistance. Obviously the PREN alone cannot be used to predict whether a particular grade will be suitable for a given application PREN = Cr + 3.3Mo + 16N, where :Cr = Chromium content:Mo = Molybdenum content. N = Nitrogen content. EN:AISI.
Reference is often made to stainless steel in the singular sense as if it were one material. Actually there are over 50 stainless steel alloys. Three general classifications are used to identify stainless steels. They are:1. Metallurgical Structure. 2.

standards for stainless steel. While the old AISI three digit stainless steel numbering system (e.g. 304 and 316) is still commonly used for the classification of stainless steel grades, new classification systems have been developed. These systems include a 1-letter + 5-digit UNS number, like S30400, as defined by SAE and ASTM.

This can be done manually by taking the thickness of the pipe, the perimeter of the pipe diameter and then the length of the pipe and multiplying all these values by the density of the stainless steel material. Each grade of stainless steel has a different density.

Steels with over 0.20% C often require a post weld heat treatment to soften and toughen the weld. 3.3 AUSTENITIC STAINLESS STEEL The austenitic stainless steels contain 16-26% Cr, 8-24% Ni + Mn The difference between 202, 304 & 316 Grade Stainless 202, 304 & 316 Grade Stainless Steel Element % 202 Grade 304 Grade 316 Grade Implications Carbon 0.15 0.08 0.08 Increase in % decreases the corrosion resistance Silicon 1.00 1.00 1.00 Manganese 7.5 to 10.0 2.00 2.00 Affects the magnetic characteristic and hardness of Iron Phosphorous 0.06 0.045 0.045 Sulphur 0.03 0.03 0.03 Chromium cvut.czHigh temperature austenitic stainless steel USA, Japan Europe JIS grade Alloy 286 S 662 86 1.4980 X5NiCrTi26-15 1.4961 X8CrNiNb16-3 1.4981 X8CrNiMoNb16-16 1.4988 X8CrNiMoVNb16-13][® weisz Steel grades equivalence tables Pág. 4
Stainless steel types 1.4301 and 1.4307 are also known as grades 304 and 304L respectively. Type 304 is the most versatile and widely used stainless steel. It is still sometimes referred to by its old name 18/8 which is derived from the nominal composition of type 304 being 18% chromium and 8% nickel. 304 L Stainless Steel
