SS PIPE GR 304 refers to a type of stainless steel pipe that meets the standards of the American Society for Testing and Materials (ASTM). Here's a brief overview: - SS: Stainless Steel - PIPE: Indicates that it's a tubular product - GR 304: Refers to the grade of the stainless steel, which indicates its chemical composition and mechanical properties. Grade 304 is one of the most widely used stainless steel grades, known for its: - Corrosion resistance - High strength - Good formability - Weldability - Low carbon content (which reduces the risk of carbide precipitation) Common applications for SS PIPE GR 304 include: - Food processing equipment - Pharmaceutical equipment - Chemical processing equipment - Marine hardware - Brewery equipment - Sanitary systems - Piping systems for water, gas, and oil Some key properties of SS PIPE GR 304 include: - Chemical Composition: - Carbon: 0.08% max - Manganese: 2.00% max - Phosphorus: 0.045% max - Sulfur: 0.030% max - Silicon: 1.00% max - Chromium: 18.00-20.00% - Nickel: 8.00-12.00% - Mechanical Properties: - Tensile Strength: 70, 000-85, 000 psi (485-585 MPa) - Yield Strength: 25, 000-30, 000 psi (170-205 MPa) - Elongation: 40-55% in 2 in (50 mm)
