STS INFORMATION STAINLESS STEEL CLUB

Character & Usage

409L

Characteristics
By adding Ti, has good weldability and drawability.
Usage
Used for automobile exhaust pipes, heat exchangers, container for which post-heat treatment is not applied.

410L

Characteristics
Excellent welding bendability by lowering the C content in 410 steel; high temperature oxidation resistance (magnetic).
Usage
Machine frames, engine exhaust pipes, boiler combustors, burners

430

Characteristics
Steel type that represents Ferrite; low thermal expansion rate and excellent drawing and oxidation resistance.
Usage
Heat resistant tools, burners, household electric appliances, sink covers, building materials, nuts and bolts, CD Bars, mesh

430J1L

Characteristics
Adding Mo,Ti and Nb results in good corrosion resistance, weldability and high temperature oxidation resistance.
Usage
Washing machine tanks, automobile exhaust pipes, electric appliance parts, three fold bottom pots.

436L

Characteristics
Adding Mo,Ti and Nb results in excellent corrosion resistance, drawability and weldability.
Usage
Automobile exhaust pipes, water supply facilities.

444

Characteristics
Due to inherent characteristics of 400-series stainless steel, drawability and weldability fall below those of 304. However, drawability is improved by using extremely minute [C+N] and the ferrite-only phase is maintained by adding Nb, a ferrite stabilizing element. As a result, this new type of steel for water tanks has an improved corrosion resistance and softness as well as higher resistance to stress, corrosion, and cracking. Furthermore, the heat treatment before and after welding can be omitted.
Usage
Water tanks, drainage Solar energy water heater, electric water heater
