Definite Guide On Stainless Steel Grades

Stainless steel is a metal alloy, made up of steel mixed with elements such as chromium, nickel, molybdenum, silicon, aluminum, and carbon. Iron mixed with carbon to produce steel is the main component of stainless steel.

Stainless steels are made of some of the basic elements found in the earth: iron ore, chromium, silicon, nickel, carbon, nitrogen, and manganese. Properties of the final alloy are tailored by varying the amounts of these elements. Nitrogen, for instance, improves tensile properties like ductility. It also improves corrosion resistance, which makes it valuable for use in duplex stainless steels.
Stainless Steel Grades are available in different series. All the different series are as under.

200 Series—Austenitic Chromium-Nickel-Manganese Alloys.

300 Series—Austenitic Chromium-Nickel Alloys

Available grades in 300 series: Type 301, Type 302, Type 303, Type 304, Type 309, Type 316, Type 321, etc..

In 300 series 304 & 316 is the most useful grade for various industrial application.

400 Series—Ferritic and Martensitic Chromium Alloys

Available Grades: Type 408, Type 409, Type 410, Type 416, Type 420, Type 430, Type 440

500 Series—Heat Resisting Chromium Alloys

600 Series—Martensitic Precipitation Hardening Alloys

Known as ph stainless steel grade.

Available Grades: 17–4 ph, 17–7 ph, 15–5 ph, 13–8 ph, etc…

Stainless Steel Usage in Medical Industry [ A-Complete Guide]

Stainless Steel is used in many industries like construction, manufacturing, automobiles, defence, aerospace and many more. Medical Industry is one of them too. The Medical Industry has many standards that every material should pass like metal should not react with any other contacting surface, strong for use, easy to sanitize and more. Here are some of the properties that make stainless steel the most preferred metal for the medical industry.  Corrosion Resistance Stainless steel is a highly corrosion-resistant property. But when it comes to the medical industry, it is very risky for patients if a small amount of rust/infection enters the human body, which can create serious medical problems. Our stainless steel solves this kind of problem very well.  Strength & Longevity   How tough stainless steel is Majorly our SS bars are used in several industries (Exp- Automobile, Aerospace, nuclear, construction & nuclear reactors certain are the industry that requires mo...
