CHARACTERISTIC

USAGE

400

409

022Cr11Ti

The cheapest model. Because of the addition of Ti element, its high temperature corrosion resistance and high temperature strength are better. Ferritic stainless steel (chrome steel)

Automobile exhaust pipe, heat exchanger, container, etc.

410

12Cr13

The representative steel of martensitic steel, although high in strength, is not suitable for use in harsh corrosive environments. Good processability, heat treatment surface hardening (magnetic)

Blades, mechanical parts, petroleum refining units, bolts, nuts, pump rods, Class 1 cutlery (knives, forks)

420

20Cr13

High hardness after quenching, good corrosion resistance (magnetic)

 

Tableware, blade, valve, ruler, turbine blade nozzle

430

1Cr17

As a representative steel of ferritic steel, it has low thermal expansion rate and excellent formability and oxidation resistance.

Heat-resistant appliances, burners, home appliances, Class 2 tableware, kitchen sinks, exterior trim materials, bolts, nuts, CD rods, screens

444

019Cr19Mo2NbTi

High corrosion-resistant ferritic stainless steel, corrosion resistance comparable to 316's excellent steel grade

Water tank, water heater, solar water heater collector board
