Stainless Steel Introduction

Stainless steel in short is also termed as ‘SS’, it is the corrosion resistant steel. The element chromium that is an alloy of the Stainless Steel is the main reason that resists the SS metal surface to get corroded. The Acromax General Trading is famous as SS profiles or Stainless steel profiles, Expansion joint and Fire sealant supplier in UAE.

Passive or protective layer

A layer of chromium oxide is present on the surface of the steel. This is a passive layer or stable layer because it does not react with any type of atmosphere further, so the steel under this coat remains intact. It can be said that the passive layer act as a protective layer of the steel against the outer environment. The SS profiles or Stainless steel profiles UAE can be obtained from Acromax General Trading.

This protective or passive coating has the property of self repair on receiving any scratches on its surface, and this is because the steel inside has chromium present in it.

Types of stainless steel

There are five types of stainless steel are Austenitic, Ferritic, Martensitic, Duplex and Precipitation hardening. The most popular stainless steel types are Austenitic and Ferritic, they produced up to the ninety five percent of the total of all types of steel production, while Austenitic Stainless Steel is alone produced up to 70 percent of the total production of all types. If you are looking for an Expansion joint supplier in UAE also then contact from Acromax general Trading.

Austenitic Stainless Steel

This stainless steel has Nickel and Magnesium as alloys, but if there is eighteen percent of chromium with eight percent of Nickel makes the nickel based austenitic stainless steel, same way if it is chromium, magnesium and nickel are added in certain proportion it becomes austenitic stainless steel. The useful property of austenitic stainless steel is that it can be welded and it is non magnetic.

Austenitic Stainless Steel applications

The Austenitic stainless steel is used to make food processing, cement and chemical plant equipment. They are also used to make kitchen sink, platforms and home appliances.

Ferritic Stainless Steel

Nickel is absent in the Ferritic Stainless Steel and in place of it carbon is added as an alloy in quantity more than with Austenitic Stainless Steel. The chromium is added up to 18 percent. The Ferritic Stainless Steel is also called Iron chrome steel. In the absence of nickel this steel is magnetic.

It used to make hot water tank and automatic exhaust. As an Fire sealant supplier UAE Acromax general trading knows its growing demand in the market.

Martensinic Stainless Steel

In this steel there is an alloy of chromium by twelve to eighteen percent along with the Carbon more than added to Ferritic Stainless Steel.

Duplex Stainless Steel

The Duplex stainless steel is made with mixture of Austenitic and Ferritic stainless steel. It is very strong.

Precipitation hardening stainless steel

It is of highest strength of all because it is made up with the process of Precipitation hardening.
