astm a106 (asme sa106)standards

Sep 03, 2024

astm a106 is a specification for seamless carbon steel pipe for high-temperature service. it has a maximum carbon content of 0.30% and a maximum manganese content of 1.20%, making it a low-carbon steel with good strength and toughness. this material is suitable for use in high-temperature and high-pressure applications, such as power generation, chemical processing, and petroleum refining. additionally, it has excellent corrosion resistance and can be used in outdoor environments without requiring additional protection.

products mainly used: apply to bending, curling and similar forming process.

the main products of steel / steel grade: gr.a, gr.b, gr.c.

diameter: 10.3 to 114.3 mm

thickness: 0.8 to 12 mm 

length: 6 m above, and, in accordance with customer demand, supply and other specifications of steel pipe
