General Characteristics
301/4310 has a lower chromium and nickel alternative to 304/4301 with high work hardening capacity. It is a good choice for applications subjected to high mechanical loading.
301/4310 is an austenitic CrNi stainless steel with high carbon and relatively low nickel content. It shows a high degree of work hardening on mechanical deformation.
This product is used in applications where corrosion resistance and a combination of high mechanical strength and good formability are needed. Due to its strong tendency to work hardening, 301/4310 can absorb an increased amount of energy during deformation. It can be delivered in temper rolled condition with different strength levels.
