Stainless Steel Grades

Stainless steels contain different properties which offer cost valuable and practicable solutions to a huge variety of purposes. The large variety of stainless steel enables the person to select the most suitable grade for the specific purpose. The generic term for stainless steel grades contain more than 10 percent chromium and other combined elements.

Stainless steel is manufactured with the combined mixture of the Titanium, Nickel, Niobium, Molybdenum and other elements. Stainless steel maintains the strength at high temperatures, resists corrosion and is easily maintained. The steel containing chromium is combined with oxygen in the environment to form an invisible or thin layer of chrome including oxide.

Common Grades of Stainless Steel

The most general stainless steel grades are:-

Type 304

This type of grade is the most flexible and extensively used stainless steel which is available in a large variety of products, finishes and forms. It contains outstanding welding and forming features. Grade 304 is used in a huge variety of applications such as architectural, industrial and transportation fields.

Type 316

Grade 316 comes on the second position after Grade 304 and contains 2-3 percent normal molybdenum bearing grade. This provides general corrosion resistant properties as compared to Grade 304.

Type 409

This type of stainless steel grade is appropriate for high temperatures. It is considered as titanium alleviated ferritic stainless steel. The main purpose of stainless steel Grade 409 is that it contains automotive weaken methods. In this type of grade, outlook is a secondary consideration as compared to mechanical properties and is corrosion resistant. The stainless steel grade 409 also includes grades such as S40920, S40910 and S40930 which are alleviated with niobium and titanium.

Type 410

Stainless steel Grade 410 is the primary martensitic stainless steel and it can be toughened by a heat treatment. It includes about 11.5 percent chromium and offers adequate corrosion resistance properties. It acquires greatest corrosion resistance and makes them lightened and hardened and after that polished.

Type 430

Stainless steel Grade 430 is considered as a ferritic stainless steel which contains certain features like non-hardenable grade, formability features, straight chromium and merging superior corrosion resistance along with mechanical properties. Another form of popular grade 430 is stainless steel Grade 430F which is the free machining edition of the grade and offered in bar variety that are more useful in mechanical screw machines. The accumulation of molybdenum enhances the resistance of corrosion.
