What is crni18-10 Stainless Steel?
CrNi 18-10 stainless steel refers to austenitic stainless steel with a chromium (Cr) content of about 17.5-19.5% and a nickel (Ni) content of about 8-10.5%. It is commonly known as 304 stainless steel in the industry and corresponds to European standard 1.4301. It can be bent, flanging, deep drawn and spun, and is easy to weld using all methods except gas welding. It is widely used in pressure equipment (such as reactors), food contact parts (tanks, pipes), medical equipment, etc. It complies with pressure equipment standards such as EN 10028-7.

Weldability
The stainless steel material 1.4301 (AISI 304 / X5CrNi18-10) can be used for all common welding processes (with the exception of gas welding). No filler material is required.
Note: When welded, the material is not resistant to intercrystalline corrosion.
Forgeability
Material 1.4301 has good forging properties. After slow heating to approx. 1150°C - 1180°C, the material can be forged in the range of approx. 1180 - 950 °C. Cooling after forging should take place in water or air.
Heat treatment and hot forming
Solution heat treatment (cooling by air or water): 1000-1100 °C
Hot forming (cooling by air): 1200-900 °C
