Metals-Piping sources alloy steel seamless pipes from one of China’s eminent pipe mill – “CHENGDE”. The raw material we mainly procure includes ASME SA335 P11, P12, P22, P5, P91, P92; ASTM A333; 15Mo3, 16Mo3, etc.

The P92 steel, also known as 9Cr-2W, is designated as UNS K92460. It may be used for the construction of ASME BPVC Section I and Section III, Division 1 according Code Case 2179-8. The P92 steel can be furnished in …

1. The Tensile Test Results for ASTM A335 P92 Pipe Bends The mechanical properties of the four pieces of ASTM A335 P92 pipe bends shall be tested and reviewed. It includes tensile strength, yield strength, elongation, as well as the …

1. General Introduction For 600 MW and 1000 MW power plant electric-unit, the P92 alloy steel is widely applied in super-critical main steam line or reheating steam line. It can be furnished in accordance with ASTM A335 P92, ASME SA335 …

1. The Development of ASTM A335 P92 In order to improve the heat efficiency of reheating steam pipeline in power plant, the reheating-temperature can be designed as high as 621°C, which is known as the super-critical temperature. The Unite States firstly …

Designated as UNS S31254 or DIN W.Nr. 1.4547, 254SMO is an Cr-Ni-Mo alloyed super austenitic stainless steel with deliberate additions of copper and nitrogen content. With high levels of chromium, molybdenum, and nitrogen, 254SMO is especially suited for high-chloride environments …

UNS N08904, commonly known as 904L with its DIN equivalent W.Nr. 1.4539, is a low carbon super austenitic stainless steel. It has superior corrosion resistance to that of conventional Cr-Ni stainless steels such as SS316L and SS317L resulting from the …

Designated as UNS S32750 or DIN W.Nr. 1.4410, Duplex 2507 is a super duplex stainless steel with 25% chromium, 4% molybdenum, and 7% nickel designed for demanding applications which require exceptional strength and corrosion resistance, such as chemical process, petrochemical, …

Designated as UNS S32205 or DIN W.Nr. 1.4462, duplex 2205 is an austenitic & ferritic two-phase Cr-Mo-Ni alloyed stainless steel which has a roughly mixed 1:1 ferrite and austenite structure. It is the most widely used duplex stainless steel grade …

Similar to SS321, stainless steel 347(SS347) is an austenitic stainless steel with deliberate addition of tantalum(Ta) and niobium(Nb) to the basic stainless steel 304(SS304). The Nb+Ta addition reduces the sensitization of carbide precipitation during welding process which also improves its …

Stainless steel 304(SS304) is the most basic stainless steel known as 18-8 grade with higher chromium and low carbon content. The low carbon content restricts carbide precipitation during welding as well as minimizes its susceptibility to intergranular corrosion. Stainless steel …

ASTM A234 WP22 Pipe Fittings Supplied to an Australian Client All fittings are made from Cr-Mo low alloy steel grade WP22 Class1(raw material mill – BaoSteel) with butt welding ends. Photos were taken before heat treatment and sandblasting & painting. …
