Characteristics and applications for Martensitic and Dual-phase tubes
Feb 01, 2018

  


Type

Stainless steel grade

Characteristics

Applications

Martensitic

410S, 410, 0Cr13, 1Cr13

Hardness is great but not suitable for harsh corrosive environment; Good machinability, hardness increases through heat treatment.

Blades, mechanical parts, oil refining components, bolts and nuts, pump lever and tablewares.

420J2, 2Cr13

Hardness increase after quenching, anti-corrosion (magnetic)

Tablewares(knives), turbine blades.

420J2, 3Cr13

Hardness increase more than 420J1 after quenching (magnetic)

Blades, nozzles, valves, steel rulers, tablewares(scissors, knives)

Dual-phase

2205

00Cr22Ni5Mo3N, S31803

Rich in molybdenum and nickel, some contains copper and tungsten, good anti-corrosion and mechanical properties.

Components used in oil refining, chemical fertilizer, papermaking, petroleum and other high temperature and corrosive chemical industry.
