Type 316

SA240 316 Stainless steel plate

On the other hand, steel workers often choose ferritic stainless steel because of its resistance to stress corrosion cracking. SAE 316 and SAE 316L stainless steel, also referred to as marine grade stainless, is a chromium, nickel, molybdenum alloy of steel that exhibits relatively good strength and corrosion resistance. SAE 440 and SAE 420 stainless steels, known also by the name “Cutlery Stainless Steel”, are high carbon steels alloyed with chromium. They have very good corrosion resistance compared to other cutlery steels, but their corrosion resistance is inferior to 316 stainless.

Typical austenitic stainless steelis susceptible to stress corrosion cracking, but austenitic stainless steel with higher nickel content has increased resistance to stress corrosion cracking. Nominally non-magnetic, austenitic stainless steel shows some magnetic response depending on its composition. Based on Chromium with small quantities of Carbon, ferritic stainless steelhas a similar microstructure to both carbon and low alloy steels.

Compared to other types of stainless steel, it is usually limited to use of relatively thin sections, due to of a lack of toughness in welds. Although, contractors use ferritic stainless steel for a wide range of applications that do not require welding. Additionally, you cannot harden ferritic steel with heat treatment.But you can use it in sea water or other aggressive conditions when you include an addition of Molybdenum. Ferritic stainless steel is also magnetic, but not as formable as austenitic stainless steel for example.

  • It has a microstructurethat includes an addition of Nitrogen, Nickel, and Manganese.
  • Austenitic stainless steel is one of the most common types of stainless steel on this list.
  • While you cannot harden it with heat, austenitic stainless steel has the useful property of retaining a helpful level of toughness and ductility when hardened to high strength.
  • The structure of austenitic stainless steel is the same as what you would find in regular steel.

What is the ASTM specification for 316l stainless steel?

316 / 316L stainless steel plates are part of the austenitic family of stainless steel and is the most widely used varieties of stainless plate. 316 grades contain a higher level of Nickel than 304 giving it an improved corrosion resistance over 304 grades.

Austenitic stainless steel is one of the most common types of stainless steel on this list. It has a microstructurethat includes an addition of Nitrogen, Nickel, and Manganese. The structure of austenitic stainless steel is the same as what you would find in regular steel. But only in a much higher temperature giving it formability and weldability.

Surgical cutting instruments are often made from 440 or 420 stainless due to its high hardness coupled with acceptable corrosion resistance. The most common types of stainless steels are austenitic stainless steels. Compared to other types of stainless steels, austenitic stainless steels are extremely high in nickel content.

Furthermore, you can make austenitic stainless steel corrosion resistant by adding Nitrogen, Chromium, and Molybdenum. While you cannot harden it with heat, austenitic stainless steel has the useful property of retaining a helpful level of toughness and ductility when hardened to high strength.
