Understanding the composition and characteristics of G-X6CrNi189 steel grade

The G-X6CrNi189 steel grade is a stainless steel grade that is commonly used in various industries due to its excellent corrosion resistance and high tensile strength. It belongs to the austenitic stainless steel family and is also known by its other common name, AISI 304.

The chemical composition of G-X6CrNi189 steel grade is as follows:
– Carbon (C): 0.08% maximum
– Silicon (Si): 1.0% maximum
– Manganese (Mn): 2.0% maximum
– Phosphorus (P): 0.045% maximum
– Sulfur (S): 0.030% maximum
– Chromium (Cr): 18.0% – 20.0%
– Nickel (Ni): 8.0% – 10.5%

The main characteristic of G-X6CrNi189 steel is its excellent corrosion resistance, specifically against chemical and atmospheric conditions. This steel grade also offers good heat resistance, making it suitable for high-temperature applications. Additionally, it exhibits high tensile strength, good formability, and excellent welding characteristics. It is non-magnetic in the annealed condition, but can become slightly magnetic after cold working or welding.

Some of the mechanical properties of G-X6CrNi189 steel grade are:
– Tensile Strength: 515 – 690 MPa
– Yield Strength: 205 – 310 MPa
– Elongation: 40% minimum
– Hardness: 92 HRB maximum

Overall, G-X6CrNi189 steel grade is widely used in the manufacture of various products such as kitchen utensils, food processing equipment, chemical equipment, and architectural applications. Its excellent corrosion resistance, high tensile strength, and good formability make it a versatile stainless steel grade for many applications.
