It covers minimum-wall-thickness, seamless cold-drawn carbon steel tubes including bending into the form of U-tubes. It\u2019s used for making a water cooling wall of the power plant boiler, it can effectively eliminate the steam film on the inner wall of the steel tube and improve the thermal efficiency of the furnace wall. There are three grades for this specification: Grade A2, B2, C2, in which B2 and C2 are commonly used.<\/p>\n<ul>\n<li>Specification: ASTM A556 B2<\/li>\n<li>\uc678\uacbd: 20mm-31.8mm<\/li>\n<li>\ubcbd \ub450\uaed8::1.1mm-35mm<\/li>\n<li>\uae38\uc774: 3m-12m<\/li>\n<li>Delivery Condition: NBK, Bright, U bending.<\/li>\n<\/ul>\n<h3><\/h3>\n<h3><\/h3>\n<h3><\/h3>\n<h3>ASTM A556 B2 Pipe Chemistry Composition<\/h3>\n<table>\n<tbody>\n<tr>\n<td width=\"142\">\ub4f1\uae09<\/td>\n<td width=\"142\">C<\/td>\n<td width=\"142\">Si<\/td>\n<td width=\"142\">Mn<\/td>\n<td width=\"142\">P<\/td>\n<td width=\"142\">S<\/td>\n<\/tr>\n<tr>\n<td width=\"142\">B2<\/td>\n<td width=\"142\">\u22640.27<\/td>\n<td width=\"142\">\u22650.10<\/td>\n<td width=\"142\">0.29-0.93<\/td>\n<td width=\"142\">\u22640.035<\/td>\n<td width=\"142\">\u22640.035<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h3><\/h3>\n<h3>ASTM A556 B2 Pipe Mechanical Properties<\/h3>\n<table>\n<tbody>\n<tr>\n<td width=\"170\">\ub4f1\uae09<\/td>\n<td width=\"170\">\uc778\uc7a5 \uac15\ub3c4 MPa<\/td>\n<td width=\"170\">\ud56d\ubcf5\uac15\ub3c4 MPa<\/td>\n<td width=\"170\">\uc2e0\uc7a5<\/td>\n<td width=\"170\">\uacbd\ub3c4 HRB<\/td>\n<\/tr>\n<tr>\n<td width=\"170\">B2<\/td>\n<td width=\"170\">410 min<\/td>\n<td width=\"170\">260 min<\/td>\n<td width=\"170\">35<\/td>\n<td width=\"170\">79 min<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h3><\/h3>\n<h3><\/h3>\n<h3><\/h3>\n<h3><\/h3>\n<p>ASTM A556, ASME SA 556steel pipe is mainly for a high-temperature heater system.
