HuaNickel UNS S42000 is a hardenable martensitic stainless steel with a similar chemical composition to 410, mainly due to the difference in carbon content.HuaNickel UNS S4200 stainless steel has a lower carbon content than 410, which allows it to achieve higher strength and hardness at lower ductility. 420 has corrosion resistance comparable to 410 and is typically used in applications that require high strength, high wear resistance, or good edge retention.
