409L (00Cr12Ti) /SUS4091

Features: The cheapest model, due to the addition of Ti element, so its high temperature corrosion resistance and high temperature strength is good. It is a ferritic stainless steel (chromium steel).

Usage: Mainly used for automotive exhaust pipes, heat switches, containers and other products that are not heat treated after welding.

410(1Cr13)/SUS410

Characteristics: The representative steel of martensitic steel, although high strength, but not suitable for use in harsh corrosive environment.

Its workability is good, and the heat treatment surface is hardened (magnetic).

Uses: Cutting edge, mechanical parts, petroleum refining device, bolt, nut, pump rod, 1 type tableware (knife, fork) in Guangdong Jieyang, Yangjiang and other areas have a certain application market.

420J1(2Cr13)/SUS420J1

Characteristics: High hardness after quenching, good corrosion resistance (magnetic).

Uses: tableware (knife), turbine blade.

420J2(3Cr13)/SUS420J2

Properties: After quenching, the hardness is higher than 420J1 steel (magnetic).

Application: Mainly in the blade, nozzle, valve, board ruler, tableware (scissors, knife) field.

430(1Cr17)/SUS430

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

Application: Mainly used in heat resistant appliances, burners, household appliances, 2 types of tableware, kitchen sink, external decorative materials, bolts, nuts, CD rod, screen and so on.
