With the development of pipeline steel plate technology and the advancement of welded pipe forming and welding technology, the application scope of pipeline welded pipe is gradually expanding, especially in the range of large-diameter group spacing. Occupying a leading position in the field of line pipes has restricted the development of stainless steel seamless line pipes. In 2004, the output of S 550 MC, QStE460TM high yield strength steel seamless line pipes was about 400,000 tons, with steel grades including X42-70, and varieties of onshore line pipes and subsea line pipes.

Pressure vessel steel plates are mainly used for manufacturing pressure vessels and other similar equipment for gas separation and gas storage and transportation in petroleum and chemical industry. Generally, the working pressure of pressure vessel steel plates ranges from normal pressure to 320kg / cm2 or even 630kg / cm2, and the temperature ranges from - 20 °C to 450 °C. In addition to certain strength, good plasticity and toughness, pressure vessel steel plates must also have good cold bending and welding properties. Q245R, q345r, 14Cr1MoR, 15CrMoR, S 550 MC, QStE460TM high yield strength steel etc. are common pressure vessel steel grades.
