ASTM A216 is a specification established by the American Society for Testing and Materials (ASTM) that covers carbon steel castings for valves, flanges, fittings, and other pressure-containing parts for high-temperature service. The standard is divided into three grades: WCA, WCB, and WCC, with WCB being the most commonly used grade.

Valve body material selection specifies the guide for carbon steel, low-temperature carbon steel, stainless steel, alloy steel, nickel-iron alloy, nickel copper, etc.

LC - stands for "low temp (wrought) carbon" with the third letter indicating grade - the higher the grade the higher the tensile/yield strength. Stainless steel is an iron-based metal that has at least 10.5% chromium (Cr).

2021年2月11日 · Carbon steel is organized into three main categories: Low carbon steel (or mild steel) is one of the most common types of carbon steel, with a carbon content between 0.04% and 0.30%. Medium carbon steel has a carbon range of 0.31% to 0.60%, and a manganese content ranging from .060% to 1.65%.

Many of the body and trim material temperatures are indicative and can vary widely depending on manufacturers: - grade, form, class of valve, end connections, duration, carbon content, annealing process, impact testing, fluid type, application, etc. Note: - Body cold working pressure rating (CWP) decreases as temperature increases.

2021年3月7日 · The ASTM A216 specification covers 3 grades of carbon steel (WCA, WCB, and WCC), which feature slight differences in terms of chemical and mechanical properties. These grades for cast valves bodies match carbon steel pipes in grades A53, A106, API 5L.

The ASTM A 216 covers 3 grades of carbon steel (WCA, WCB, and WCC), which feature slight differences in terms of chemical and mechanical properties. These grades for cast valves bodies match carbon steel pipes in grade A 53, A 106, API 5L .

Global Supply Line stocks and indents a large range of carbon steel valves in low temperature carbon steel such as forged ASTM A350 LF2 and it’s cast equivalent ASTM A352 LCB. Higher grades such as ASTM A352 LCC and Alloy (Nickel) based forged carbon steel A350-LF3 and it’s cast equivalent A352-LC3 are also available on an indent basis.

Above +800°F (+425°C) specify carbon content of 0.04% or greater. Corrosive or non-corrosive services to +800F (+425°C). Good resistance to hot sulfuric acid to +800F (+425°C). Weldable grade. Good resistance to corrosion by all common organic acids and salt water. Also highly resistant to most alkaline solutions to +750°F (+400°C).
