Introduction

Overview

Martensitic stainless steels are built around grade 410 composition of iron, 12% chromium, and up to 1.2% carbon. Like Ferritic stainless steel, it contains little to no nickel content. The typical martensitic grades are 1Cr13, 3Cr13, etc.. They can be high- or low-carbon steels, hardenable through heat treatment, specifically by quenching, or by quenching and tempering.

Features of Martensitic Stainless Steel

Martensitic stainless steel features high strength, but poor plasticity and weldability. Due to the high carbon content, Martensitic stainless steel features high strength, hardness and wear resistance. Since its corrosion resistance is slightly poor, it is generally used to those parts that have special requirements on mechanical properties but relatively low requirements on corrosion resistance, such as springs, steam turbine blades, hydraulic press valves, etc. This type of steel is generally used after quenching and tempering.

Remarks

Tempered martensitic stainless steel features good hardness and high toughness, largely applicable to medical tools, such as scalpels, razors and internal clamps. Untempered martensite is low in toughness and therefore brittle, confining the use to very limited areas.
