About Stainless Steel

Stainless steel is the name of a high alloy steel used mainly for its anti-corrosion properties. The main characteristic of the stainless steel family is that they all contain a minimum of 10.5 percent of chromium. This enables the steel to withstand corrosive atmospheres or erosive chemical environments.

What is Stainless Steel?

Stainless steel does not readily corrode, rust or stain with water as ordinary steel does, but despite the name it is not fully stain-proof, most notably under low oxygen, high salinity, or poor circulation environments. There are different grades and surface finishes of stainless steel to suit the environment the alloy must endure. Stainless steel is used where both the properties of steel and resistance to corrosion are required.

History of Stainless Steel

Sheffield, England born Harry Brearly discovered stainless steel in 1913. In an experiment, he found that steel’s corrosion
resistance increased when the chromium content is raised to 12 percent or more. He is seen as the person who laid the
foundation for the development of various stainless steel grades.

What is Corrossion?

Stainless steel is susceptible to certain types of corrosion despite the fact that one of the main reasons for using stainless steel is its resistance to corrosion. The different kinds of corrosion affecting stainless steel are:
General Corrosion, pitting corrosion, crevice corrosion, stress corrosion cracking, sulphide stress corrosion cracking, intergranular corrosion, galvanic corrosion and contact corrosion.

Stainless Steel Categories

Stainless steel is divided into 5 main categories. These are Austenitic, martensitic, ferritic, duplex and precipitation hardening.
200 Series Austenitic – Alloys: 201, 202, 203, 204 & 205 is a chromium-nickel-manganese alloy with high strength in the annealed. This series is non-magnetic, not heat treatable and has excellent formability for sever forming applications. It is used in structural applications and for the manufacture of washing machine tubs.

Stainless steel or corrosion-resistant steel is a kind of metallic alloy that is found in a variety of forms. It serves our practical needs so well that it is difficult to find any sphere of our life, where we do not use this type of steel. The major components of stainless steel are: iron, chromium, carbon, nickel, molybdenum and small quantities of other metals.

 

Application

Stainless steel is a very versatile and useful material used in a wide variety of applications. It is used in the following fields:

  • Cutlery and kitchenware
  • Home appliance
  • Chemical processing and oil & gas industries
  • Power generation
  • Food production
  • Architecture, building and construction
  • Medical applications
  • Automotive parts

China Hit With Heavy Cold-Rolled Steel Duties, Korean and Russian Imports Mostly Unharmed

Today, the Commerce Department announced its affirmative preliminary determinations in the countervailing duty investigations of imports of cold-rolled steel flat products from Brazil, , India, and Russia, and its negative preliminary determination in the CVD investigation of imports of cold-rolled steel flat products from South Korea.

The investigations cover cold-rolled, flat-rolled . It should come as no surprise that the largest subsidies are being assigned to Chinese importers.

Chinese Imports Take a Hit

In the China investigation, Commerce preliminarily determined that mandatory respondents Angang Group Hong Kong Co., Ltd. and Benxi Iron and Steel (Group) Special Steel Co., Ltd. and, a non-cooperative exporter — Commerce’s term for companies that do not respond to requests for information in the investigation — Qian’an Golden Point Trading Co., Ltd., received whopping subsidy rates of 227.29%.

All other exporters of cold-rolled steel flat products from China will be subject to that same subsidy rate of 227.29%. The rates are based on adverse facts available. Commerce determined that the Government of the People’s Republic of China, and the mandatory respondents, did not fully cooperate in the investigation.
