Stainless Steel Grades Directory

AISI 307Si | EN 1.4370 | DIN X15CrNiMn18-8 is a superalloyed, fully austenitic stainless steel alloy. It is suitable for welding difficult to weld (martensitic, duplex) austenitic, low alloy or manganese stainless steels. The high manganese content makes the weld metal very resistant to hot cracking with good ductility.

AISI 321H | EN 1.4878 | DIN X8CrNiTi18-10 is an austenitic, heat-resistant chromium-nickel stainless steel which, due to its resistance to scale, is suitable for use at temperatures up to 850 °C. AISI 321 H is very similar in structure and quality to AISI 321 steel and therefore has good corrosion resistance.

AISI 416Se is a martensitic stainless steel that, due to the selenium (Se) and sulfur (S) content, provides better machinability than other similar stainless steels. However, this inclusion reduces the weldability, formability and corrosion resistance of this grade to a level lower than that of AISI 410.
