ASTM A106 is applicable to seamless carbon steel pipes used in high-temperature environments. ASTM A106 pipes are manufactured in grades A, B, and C. A106-A is equivalent to domestic grade 10 steel, A106-B is equivalent to domestic grade 20 steel, and it is a commonly used steel material both domestically and internationally. Seamless steel pipes of ASTM A106 are mainly applied in industries such as construction, mechanical processing, electrical equipment, and petrochemicals.
