Химические и механические требования к углеродистой стали. ASTM A216 WCB
Jan 21, 2024
Для клапанов из углеродистой стали WCB ASTM A216 чаще всего используется для литья подложки корпуса и крышки клапана, а также других несущих деталей.
химические требования
1. All values are maximums.
2. For lower maximum sulfur content, see Supplementary Requirement S52
3. Specified Residual Elements- Except when Supplementary Requirement S50 is specified, the total content of these elements is 1.00 % maximum.
4. For each reduction of 0.01 % below the specified maximum carbon content, an increase of 0.04% manganese above the specified maximum will be permitted up to a maximum of 1.10 % for WCA.1.28 % for WCB and 1.40 % for WCC
Tensile Requirements
The equivalent material in forged type is ASTM A105N(refer to the standard accordingly).
