Martensitic grades, like their carbon steel equivalent, maintain extremely high strength at room temperature. Precipitation-hardening grades have good room-temperature formability and can reach 260 KSI in strength after heat treating while maintaining corrosion resistance.
Difference between 300 and 400 Series Stainless SteelHowever, if we were to compare both the series as a whole, the austenitic class 300 series stainless steel would outperform the martensitic class series 400. This is for several reasons. First, the use of nickel and chromium is high in the 300 series, which means the resistance of the alloy to corrosion also becomes higher.
Martensitic stainless steels are used for fasteners and pump shafts. Precipitation hardening stainless steels are used for valves, gears, and petrochemical equipment. And duplex stainless steels are used across applications similar to austenitic and ferritic stainless steels. Examples include marine environments and pollution control equipment.
How to Weld Stainless Steel - The Definitive Guide for Martensitic stainless steel gets very hard and has a high strength. Martensitic stainless steel can be identified by the AISI 400 series. Usually, it contains 11.5% up to 18% chromium and up to 0.15 up to 1.2% carbon By controlling the preheat temperature and interpass temperatures cracks can be avoided when welding martensitic stainless steels.
Know Your Martensetic Stainless Steel - RyersonFor martensitic stainless steels, that make up includes carbon and iron. Characteristics:Moderate levels of corrosion resistance, high hardenability and machinability, poor formability and can be welded with caution. Can be heat treated to provide a range of mechanical properties.
Martensitic stainless steels can provide resistance to CO2 corrosion while providing good mechanical and toughness properties. The evolution of martensitic stainless steels is grounded in improving their resistance to sulfide stress cracking and chloride SCC.
Martensitic stainless steel and precipitation hardening Martensitic steel grades and precipitation hardening (PH) stainless steels are heat treatable and can therefore provide hardness and strength in a wide range of applications. Allowing to workability they are supplied in solution annealed condition.

I. Stainless Steel GradesII. Stainless Steel ClassificationIII. Stainless Steel Mechanical PropertiesIV. Detailed Introduction to Stainless SteelStainless Steels Welding Guide - Lincoln ElectricMartensitic stainless steels are similar in composition to the ferritic group but contain higher carbon and lower chromium to permit hardening by heat treatment. Types 403, 410, 416 and 420 are representative of this group. Duplex stainless steels are supplied with a microstructure of approximately equal amounts of ferrite and austenite.
Martensitic stainless steel mainly contains 12~18% Cr, and the amount of C can be adjusted according to needs, generally 0.1~0.4%. For tools, C can reach 0.8~1.0%, and some are to improve the stability of tempering resistance by adding Mo, V,and Nb etc.
Weldability of Materials - Stainless Steel - TWIMartensitic stainless steel The most common martensitic alloys e.g. type 410, have a moderate chromium content, 12-18% Cr, with low Ni but more importantly have a relatively high carbon content. The principal difference compared with welding the austenitic and ferritic grades of stainless steel is the potentially hard HAZ martensitic structure and the matching composition weld metal.
What is Martensitic Steel? - AZoMApr 10, 2020 · Martensitic stainless steel is very responsive to multiple forms of heat treatment which can increase hardness, strength and corrosion resistance. Martensitic stainless steel's strength and corrosion resistance are ideal for marine, industrial, and medical applications while its versatility can make it the solution to a number of problems.
Martensitic stainless steel is a stainless steel alloy with a carbon content of less than one percent. Instead, martensitic stainless steel primarily consists of iron and chrome, plus smaller amounts of nickel, copper, and other metals. This special blend of metals gives this material several advantages over traditional carbon steel, including strength and corrosion resistance.
