What To Know Before Buying Stainless Steel Online

Stainless steel contains iron and a minimum of 10 percent chromium. It is highly preferred due to its corrosion resistance, modern appearance, and sanitary qualities. Even though stainless steels are more expensive than aluminum, they require little maintenance and replacement costs. In addition, stainless steels are more durable than most sheet metals. Although the corrosion resistance of stainless steels comes from the presence of chromium, other elements are added to improve other properties. These elements change the microstructure of steel. Stainless steels are grouped into families due their different metallurgical structures. The selection of a given type and grade of stainless steel must meet the corrosion resistance requirements. Here are important details to know before buying Stainless Steel Online.

The Five Main Families of Stainless Steels

  • Austenitic stainless steels: They contain a minimum of 6 percent nickel and 16 percent chromium. They range from the super grades such as 904L to the basic austenitic like 304. Austenitic steels are non-magnetic and cannot be hardened by heat treatment.
  • Ferritic stainless steels: They contain about 10 to 18 percent chromium. Ferritic stainless steels are known for their moderate corrosion resistance and poor fabrication properties. They are used in the annealed condition and cannot be hardened by heat treatment.
  • Martensitic stainless steels: They are magnetic, have poor weldability and moderate corrosion resistance. Examples of martensitic stainless steel include 416 and 410.
  • Duplex stainless steel: They have low nickel and high chromium contents. Since they have ferrite and austenite in their structure, duplex stainless steels feature properties of both classes.
  • Precipitation hardening grades: They contain nickel and chromium. They are supplied in a solution treated a condition that allows the alloy to be machined.

Top Factors to Consider When Choosing Stainless Steel Grades

When choosing a particular grade of stainless steel, it is important to consider the primary properties needed such heat resistance, corrosion resistance, mechanical properties, availability, fabrication characteristics, and product cost. Selecting the right grade will ensure the final product will have a long life combined with cost effective fabrication and installation.
