ASTM A815 Stainless Steel Pipe Fittings cover a variety of stainless steel materials, including ferritic stainless steel, ferritic/austenitic duplex stainless steel, and martensitic stainless steel. Different grades have specific chemical compositions and properties to adapt to various use environments and requirements. Common grades include S31803 (22Cr-5Ni-3Mo) and others.

• Chemical composition analysis: All pipe fittings produced in accordance with ASTM A815 standards must be chemically tested before leaving the factory to ensure they meet the specified chemical composition range.
• Mechanical property testing: Including tensile testing, hardness testing, impact testing, etc., to verify whether the strength, toughness, plasticity and fatigue resistance of the product meet standard requirements.
• Non-destructive testing: Use ultrasonic testing, magnetic particle testing, penetrant testing and other methods to check for cracks, inclusions or other potential defects inside the pipe fittings.
• Dimension measurement and appearance inspection: Ensure product dimensional accuracy, and conduct comprehensive assessment of appearance quality, label clarity and other aspects.
