The 1.4301 and 1.4307 stainless steels are also known as 304 and 304L grades, respectively.
Type 304 is the most widely used and widely used stainless steel. It is still sometimes mentioned
Made up of its old name 18/8, this was made up of 18% from the nominal Type 304 Chromium and 8% nickel.
304 stainless steel bar, also known as UNS S30403 and 304, is a material with low carbon content
The Type 304 version is generally preferred because it is the “free working” version. Class of 304
With good strength and corrosion resistance, it is the ideal choice for almost all products
Industry. Cold working would have increased hardness and strength at the same time, but it didn’t
Reacts to heat treatment.
Stainless steel austenitic chromium nickel steel 1.4301 has good corrosion resistance
(especially in the case of natural environmental media and lack of large amounts of chlorine
Salt concentration and seawater) and weldability. Applications that use acid must be inspected
Alone. However, 1.4301 weld after unstable intergranular corrosion. good polishing and deep drawing properties,petrochemical industry, automobile industry
