Main Material: 15crmo, 20 #, 35 #, 45 #, 20G, 40Cr, 20Cr, 16Mn-45Mn, 27SiMn, Cr5Mo, 12CrMo (T12), 12Cr1MoV, 12Cr1MoVG, 10CrMo910, 15CrMo, 35CrMo, 40CrMo and so on. Now I have a lot of alloy pipe, pressure pipe stock 15crmo, will be preferential prices, wholesale and retail ways, to provide you with fast quality service 15crmo offer, welcome new and old customers to negotiate, Power Conference. Note: 1, large supply for your special wall thickness, materials seamless Baosteel 15crmo, cold drawn precision tubes and a variety of thermal expansion. 2. Our aim is: Let you save money, save time, peace of mind. Company can build all kinds of special specifications, special materials seamless, timely delivery, low price, excellent quality, with a book or a copy of the original material, holiday business as usual, and agents Automotive, fire operation 15crmo standard , a large quantity can be shipped directly to steel mills. Surface heat treatment is by changing the surface of the tissue 15CrMo alloy steel bar to change the surface properties of a heat treatment. Surface hardening eleven surface tissue change, without changing the chemical composition of the surface heat treatment. It can be used high-frequency, intermediate frequency or frequency current induction heating or flame heating ways. Their common feature is to try to make 15CrMo alloy steel bar surface rapidly heated to quenching temperature, and in the heat of the heart has not yet spread to parts department, then quickly cooling, high surface hardness, toughness and heart Ministry is still high. 15crmo, Katherine source of steel (certified), Zhongshan 15crmo provided by source Pipe Co., Ltd. Liaocheng trillion. Liaocheng Katherine source Pipe Co., Ltd. (www.lczygg.com) Shandong Liaocheng, steel leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
