The role of niobium and titanium in stainless steel
Source:Xinsteel   Date:2020-04-29

Titanium is a strong deoxidizer in steel. It can make the internal structure of the steel dense and refine the grain strength; reduce the aging sensitivity and cold brittleness. Change welding performance. Adding appropriate titanium to Cr18Ni9 austenitic stainless steel can avoid intergranular corrosion. For example, 321 stainless steel plate, 321H stainless steel plate, etc.
Niobium can refine grains and reduce the overheating sensitivity and temper brittleness of steel, and increase the strength, but the plasticity and toughness decrease. Adding niobium to ordinary low alloy steel can improve the resistance to atmospheric corrosion and hydrogen, nitrogen and ammonia corrosion at high temperature. Niobium can improve welding performance. Adding niobium to austenitic stainless steel can prevent intergranular corrosion. For example, 347 stainless steel plate, 347H stainless steel plate. We Xinsteel glad to offer you stainless steel plate 321, 321H, 347, 347H ready stock and rolled freshly according to your request, with thickness of 1mm-200mm, Maximum width of 4200mm, maximum length of 12000mm. also can cut and bend to flat, round, cylindrical.,etc to fully meet your request.
