Steel Information

Chemical Composition Table

Our all products as well as their internal components are developed from Stainless Steel confirming to AISI 316 Grade Stainless Steel which is completely anti-corrosive and resist the adverse effects of chemicals. Most important factor which effect to cost of any product is its Raw Material.

The following table presents main elements (forming the Chemical composition) of AISI 316 Grade Stainless Steel as compared to other cheaper grade steel such as 304, 202 or even claimed to be 316 by many other manufacturers.

 

Element %	202 Grade	304 Grade	316 Grade	Implications
Sillicon	1.00	1.00	1.00	-
Manganese	7.5 to 10.0	2.00	2.00	Affects the magnetic characteristic and hardness of Iron
Phosphorus	0.06	0.045	0.045	-
Carbon	0.15	0.08	0.08	Increase in percentage decreases the corrosion resistance.
Nickel	4 to 6	8.0 to 10.5	10.0 to 14.0	Nickel provides corrosion resistance, increases strength in both high & low temperature, increases toughness in low temperature and lowers the effects of work hardening. Thus higher percentage makes the steel superior in quality.
Sulphur	0.03	0.03	0.03	-
Chromium	17.0 to 19.0	18.0 to 20.0	16.0 to 18.0	Addition of 12% forms stainless steel from ordinary steel. removes the corrosive effect of Carbon. Forms a passive film which prevents oxidation & consequent corrosion.
Molybdenum (MOLY)	Nil	Nil	2 to 3	Molybdenum increases the corrosion resistance to chiorides and sulphates including sulfurous acids in pulp industries. It has a superior tensile strength at high temperature as compared to 304 Grade steel. This element can resist major chemical reaction and thus being a very costly element.

 

Key Features Of AISI 316 Grade Stainless Steel

• It has remarkable creep strength and Rupture strength.
• It can withstand the corrosion caused by atmospheric / environmental or major chemical reactions.
• It repels the Bacteria which makes it ideally suitable material for the venue such as Hospitals, educational Institutes, Hotels and even at home and office where higher degree of hygiene is required.
• Due to its natural finish, product does not require regular cleaning or maintenance making it most suitable for public places.
• It can resist high temperatures without going under any deformity which makes it highly recommended for fire safety doors in any building.
