Phosphorus (P)

Phosphorus (P) flanges, Pipe Fitting, Steel Pipe, Heat Exchanger and Reducer, Gasket, Tee, Pipe Fitting, Tube Plate, have all specifications. With many yeas production experience, strict control ASTM 11Q chemical composition and ASTM 11Q mechanical properties.

Production specification
Data center describes many of the common steel models, we can not determine the company's warehouse has all types of steel products inventory or raw materials.

Phosphorus (P) standard

Phosphorus (P)
Phosphorus in steel solid solution strengthening and cold hardening effect is strong, as an alloy elements to low alloy steels, can improve the strength and the steel atmospheric corrosion resisting performance, but reduce its cold stamping performance. Phosphorus and sulfur and manganese joint use, can increase the steel is cutting performance, increase the surface of the product quality, used for easy cutting steel, so easy to cut steel phosphorus is higher also. Phosphorus soluble in ferrite, although can improve the strength and hardness of the steel, the largest of the serious harm is segregation, increase the brittleness, significantly reduce steel plasticity and toughness, cause easily when cold steel in crisp crack, also called "ductile-brittle" phenomenon. Phosphorus on welding sex also have adverse effects. P is harmful element, should be kept under strict control, general content is not more than 0.030%-0.040%.
