420 stainless steel is equivalent to 3Cr13 of Martensitic Steel in china.
Type 420 is a martensitic stainless steel that provides corrosion resistance similar to Type 410 plus increased strength and hardness. It is magnetic in both the annealed and hardened conditions.
Maximum corrosion resistance is attained only in the fully hardened or fully hardened and stress relieved condition. It is never used in the annealed condition.

420 Martensitic steel is similar to Brinell high chromium,which was the earliest stainless steel. 420 stainless steel is higher hardness,lower price,with a certain wear resistance and corrosion resistance.It is suitable for the work environment that needs general requirements for stainless steel.It is commonly used for manufacture of steam, water and oxygen, chemical resistance to atmospheric corrosion and acid components.For higher hardness than 2Cr13,it is also used for knife tools,nozzle,valve seat,valve,etc.
