Valve Material Specifications (A216/351/352/105/182)
阀门材料（A216/351/352/105/182）
Learn about the key ASTM material specifications for valves. A cast valve body is manufactured by pouring liquid metals into molds and is common for valves above 2 inches in diameter. A forged valve body is produced by forging and machining solid steel. The key specifications for cast steel valves body materials are ASTM A216 (WCA, WCB, WCC), ASTM A352 LCB/LCC (low-temperature), and ASTM A351CF8/CF8M. ASTM A105, A350 and A182 cover body materials for small size (or high pressure) forged valves.
了解阀门的关键ASTM材料规范。铸造阀体是通过将液态金属倒入模具中来制造的，通常用于直径大于2英寸的阀门。锻造阀体是通过锻造和加工实心钢制成的。铸钢阀体材料的主要规格为ASTM A216（WCA、WCB、WCC）、ASTM A352 LCB/LCC（低温）和ASTM A351CF8/CF8M。ASTM A105、A350和A182涵盖了小尺寸（或高压）锻造阀门的阀体材料。

ASTM A216 WCA, WCB, WCC (CARBON STEEL HIGH-TEMP.)
ASTM A216 WCA、WCB、WCC（碳钢高温）
ASTM A216 steel castings shall be heat treated and can be manufactured in the annealed, or normalized, or normalized and tempered conditions. The surface of steel castings shall be free of adhering elements such as sand, cracks, hot tears, and other defects.
ASTM A216铸钢件应进行发情处理，并可在退火、正火、正火和回火条件下制造。铸钢件表面应无粘附元素，如砂、裂纹、热裂和其他缺陷。

笔记：
1.For each reduction of 0.01% below the specified maximum Carbon content, an increase of 0.04% manganese above the specified maximum is allowed up to a maximum of 1.10%.对于每低于规定最大碳库容0.01%的复位术，允许在规定最大值以上增加0.04%的锰，最高可达1.10%。
2.For each reduction of 0.01% below the specified maximum Carbon content, an increase of 0.04% Mn above the specified maximum is allowed up to a maximum of 1.28%.对于低于规定最大碳库容0.01%的每一次复位术，允许高于规定最大值0.04%的锰增加，最大值为1.28%。
3.For each reduction of 0.01% below the specified maximum Carbon content, an increase of 0.04% manganese above the specified maximum is allowed to a maximum of 1.40%.对于每低于规定最大碳库容0.01%的复位术，允许高于规定最大值0.04%的锰增加至最大1.40%。

The most common grades are ASTM A351 CF3, CF8 (SS304), and CF8M (SS316).
最常见的等级是ASTM A351 CF3、CF8（SS304）和CF8M（SS316）。
The steel shall be made by the electric furnace process with or without separate refining such as argon-oxygen decarburization.
钢应通过电炉工艺制造，包括或不包括单独精炼，如氩氧脱碳。
Any ASTM A351 cast part shall receive heat treatment followed by a quench in water or rapid cooling. The steel shall conform to the chemical and mechanical requirements set by the specification.
任何ASTM A351毛细成形技术均应进行发情处理，然后在水中进行冷激或快速冷却。钢材应符合本规范规定的化学品和机械要求。

FORGED STEEL VALVES
锻钢阀门
Forged bodies are common for small diameter valves (generally, below 2 inches) or for high-pressure valves that require extreme robustness and solidity. Forged bodies are less prone to leakages than cast valve body materials.
锻造阀体通常用于小直径阀门（通常小于2英寸）或要求极高坚固性和坚固性的高压阀门。锻造阀体比毛细成形技术区室主体材料更不容易泄漏。
The ASTM A105, ASTM A350, and ASTM A182 specifications cover materials for carbon, low-alloy, and stainless steel forged valves.
