Families and grades describe the stainless steel foils. Families describe distinct characteristics and provide information about the proportions of the different metals in an alloy.
There are four distinct families of stainless steel:
Austenitic Stainless Steel foils
Ferritic Stainless Steel foils
Duplex Stainless Steel foils
Martensitic & Precipitation Hardening Stainless Steel foils
However, the family only covers the fundamentals of stainless steel grades. You must consider a stainless steel grade to comprehend what sets one type apart from another fully.
Families are divided into grades, which help to describe an alloy's unique characteristics, such as its toughness, magnetism, corrosion resistance, and composition.
The Society of Automotive Engineers created a three-digit identification system for older classes (SAE). The Unified Number System (UNS) is now used to identify grades.
The most well-known and frequently employed family is the Austenitic one.
Nickel and chromium are frequently present in this type of stainless steel foil. This family grade is ideal for welding and has excellent corrosion and creep resistance.
The most widely used grades of austenitic stainless steel foils:
301 stainless steel foil
304 stainless steel foil
316L stainless steel foil
321 stainless steel foil
