Stainless Steel

About

Taemyung Steel supplies a full range of stainless steel materials, included angle, beams, channel, bar, plate, pipe, tube, grating, expanded and perforated metal and grip strut. Stainless steel is a modern alloy developed in the early 1900’s after metallurgists discovered that chromium-iron alloys displayed superior corrosion resistance to carbon steel alloys. The first products using stainless steel were produced in 1908 and the first patents were granted in 1912. Stainless steel, which combines the high strength, hardness, workability and formability of steel with high corrosion resistance and smooth surface finish, is one of the most popular steel alloys and is used in applications throughout industry. It is a low cost material and is 100% recoverable and recyclable.

The corrosion resistance that is unique to stainless steel is the result of a transparent passive film of chromium oxide forms on the surface of the steel and protects it from oxidation. Higher chromium levels increase the corrosion resistance of the steel, but it creases the brittleness of the metal, making it hard to work with.

Stainless steel sheet is one of the most commonly used forms of stainless steel and is used to manufacture parts and products for a wide range of applications. Its properties:



  • High corrosion resistance

  • High strength

  • High toughness and impact resistance

  • Temperature resistance from cryogenic to high heat

  • High workability, including machining, stamping, fabricating and welding

  • Smooth surface finish that can be easily clean and sterilized

Ensure that products manufactured using stainless sheet perform well. These include stamped and machined products ranging from fasteners and fittings, to sinks and drains, to tanks. It is used in all industries, especially corrosive and high heat environments such as chemical, petrochemical and food processing, fresh and salt water marine, engines and motors.

Stainless sheet is primarily a cold rolled product, but is available as hot rolled if needed. It can be sourced from coil in gauges from 26GA thru 7 GA, and in widths up to 72” wide. Stainless sheet can have a smooth 2B mill finish, 2D rough, or in a polished finish.
