Such as the amount of large martensitic stainless steel tube is the first to use the traditional 2Cr13 steel, in recent years abroad developed a super martensitic stainless steel (S13Cr also known as soft martensite or weldable martensitic stainless steel), mainly carbon The amount of alloy is reduced from 0.01% to 0.07%, the typical alloy content is 12% ~ 13% Cr, 2.0% ~ 6.5% Ni, 0 ~ 2.5% Mo.[url=https://steelsheetprices.com/]jiangsu steel Group Co. Ltd[/url] Because of the high yield strength (��0.2 550 ~ 850MPa), the impact toughness is good, the corrosion resistance is good, and the welding method can be used in the conventional way. The total cost is 35% ~ 40% lower than that of the duplex stainless steel, So in the offshore oil and gas industry is widely used, the global consumption of about 500,000 t, only in 2001 to produce 21.25 million t, accounting for 71% of Japan's stainless steel pipe.[url=https://steelsheetprices.com/steel-coil/]hot sale stainless steel coil[/url] At present, China's annual consumption of less than 10,000 t, from the use of the level of view, the equivalent of foreign 20th century 70 ~ 80's situation, that is mainly dependent on carbon and manganese steel to add corrosion inhibitor, not only frequent accidents, operating costs Stainless steel seamless high.[url=http://stainlesssteelcoilprice.com/stainless-steel/871.html]����ݧ�էߧ�ܧѧ�ѧߧߧѧ� �ߧ֧�اѧӧ֧��ѧ� ���ѧݧ� 430 ��֧ߧ� �٧� �ܧ�[/url] Especially in recent years, Chongqing high H2S content of natural gas blowout after the vicious accident, oil and gas drilling industry on the corrosion-resistant steel pipe has more stringent quality requirements and more urgent market demand. Super Martensitic stainless steel tube is to meet the needs of the market in urgent need of the development of products.[url=http://304stainlesssteelsheet.com/steel-plate/2717.html]stainless 316L hex bar best price[/url]
