Steels of that group are martensitic. Steel 30X13 has a good corrosion resistance (but not against sea water), usually used for applications which demand high plasticity and experience impact loads. Steel is suitable for production of fastenings and other parts used in atmospheric and humid environments. Recommended temperature range is -50°C to +480°C. Weldability is rather limited. Before welding steel should be annealed, during the welding steel should be heated up to 350-600°C (depends on the complexity of the weld). After welding it is necessary to do tempering.

440C is a high carbon straight chromium high hardenability martensitic stainless steel, generally supplied in the annealed condition with a maximum Brinell hardness of 269 (Rc29) or annealed and cold drawn with a maximum Brinell hardness of 285 (Rc31).Characterised by good corrosion resistance in mild domestic and industrial environments, including fresh water, organic materials, mild acids, various petroleum products, coupled with extreme high strength, hardness and wear resistance when in the hardened and tempered condition. 440C due to its excellent hardenability is capable of being through hardened up to Rc60 depending upon carbon content and section size. Small sections can be air cooled and quite large sections oil quenched for maximum through hardness.Used for parts requiring a combination of excellent wear resistance, plus reasonable corrosion resistance. Typical applications are: Ball Bearings and Races, Bushings, Cutlery, Chisels, Knife Blades, Pump Parts, Surgical Instruments, Valve Seats etc.

Description AISI (418) is a hardenable chromium-nickel-tungsten martensitic alloy that is designed for services at temperatures up to 1200 °F in highly stressed parts. This steel is an extremely deep-hardening grade and is used where slightly superior creep strength and resistance to tempering and stress-corrosion cracking are desired in addition to the general properties of the 12% chromium stainless steels. Applications engine braces, turbine exhaust components, exhaust struts, stiffeners, and ducts, Compressor blades, vanes, disks, shafts, wheels, fasteners, gas turbine and jet engine components, steam turbine buckets and blades as well as compressor parts in gas turbines and high temperature bolts.
