EN 1.4376 has higher strength than standard 304/1.4301 and a lower nickel content, making it a cost-effective and lightweight austenitic product for the automotive industry. It has been used in automotive applications for over 10 years.
EN 1.4376 is an austenitic stainless steel, which belongs to the austenitic low-nickel CrMn stainless steel family, in which manganese replaces part of the nickel that is normally alloyed to CrNi standard grades. This variant has low carbon content. Due to its high nitrogen content, EN 1.4376 has increased mechanical strength. EN 1.4376 is optimized for strong work hardening on mechanical deformation.
The corrosion resistance of the austenitic CrMn grades is usually slightly below that of the austenitic CrNi standard grades. EN 1.4376 is used in applications where a combination of high mechanical strength and good formability, as well as corrosion resistance, is needed. Due to its strong tendency to work hardening, EN 1.4376 can absorb a high amount of energy during deformation. It can be delivered in the temper rolled condition with different strength levels.
