Product Description

SA-210C is ASME boiler materials, a seamless carbon steel pipe widely used for water cooling wall, economizer of boiler parts. Its chemical composition is simple, except for a higher carbon and manganese content, and the rest composition is similar to 20G, so the yield strength is about 20% higher than 20G while the plasticity and toughness are equivalent to 20G. Because of a simple production process and good properties. It is mainly used for water-cooled walls, economizers, low-temperature super heater and other parts with working temperatures lower than 500 degrees centigrade.

Equivalent Standard: UNI 5462-64, DIN 17175, EN 10216-2, BS 3602 Part I, NF A 49-213, NBR 5592, ASTM A106, GB 5310, ASTM A178, JIS G3456, JIS G3461

Equivalent Materials: 20G ST45.8 STB52 19Mn5 SA-210C ASTM 106 Gr. C.

Available size from 1/2 inch to 5 inch. [12.7 to 127 mm] in outside diameter and 0.035 to in. 0.500 [0.9 to 12.7 mm] in minimum wall thickness. Length in 2m,3m,5.8m,6m or custom.
