Data sheet material 1.4833 / AISI 309S

X12CrNi23-13

Austenitic heat-resistant stainless steel

Brief description

The material 1.4833 or AISI 309S is a heat-resistant austenitic chromium-nickel steel. However, its availability is significantly lower than that of comparable heat-resistant austenitic steels such as 1.4828, 1.4841 or 1.4845.
