UGI 4435 IRH Solution Annealed
UGI 4435 IRH Solution Annealed introduction
UGI 4435 IRH is an austenitic stainless steel (not magnetic) with a high Mo content and produced by a special method to optimize its cleanliness. Its composition provides it with very good corrosion resistance and is perfectly suited for prolonged contact with the skin. This grade also offers improved polishability, thanks to its inclusion population and its microstructure, adapted and controlled.
The chemical composition of UGI 4435 IRH is optimised to ensure primary ferritic solidification limiting hot workability problems and risks of crack formation at high temperature during welding, while providing it with a structure almost 100% austenitic at room temperature.
Grain size as per ASTM E-112: ≥ 5 (≥ 4 if need of guarantee of residual ferrite
Cleanliness as per DIN 50602, "M" method:
Sulphides (SS) + Oxides in Alignment (OA) + Silicates (OS): less than 4%
Dispersed or globular oxides (OG): less than 1%
Equivalent material: DIN 1.4435, ASTM 316L00109, JIS SUS316L, AISI 316 L00109, AFNOR X2CrNiMo18-14-3, EN 1.4435, BN2 1.4435, DIN X2CrNiMo18-14-3, EN X2CrNiMo18-14-3
