Pressure vessel steel plate is mainly used for manufacturing pressure vessel or other similar equipment for gas separation and gas storage and transportation in petroleum and chemical industry. Generally, the working pressure of Q690C carbon steel material pressure vessel steel plate is 320kg / cm2 or 630kg / cm2 under normal pressure, and the temperature is within the range of - 20-450 ° C. It is required that the pressure vessel steel plate has not only certain strength and good plasticity and toughness, but also good cold bending and welding performance.

TMCP process is an indispensable technology for our production of low alloy high strength wide and Q690C carbon steel material thick steel plates. TMCP process can produce steel with high strength and toughness without adding too many alloy elements and complex subsequent heat treatment. TMCP is a process that can save alloy Q690C carbon steel material and energy and is beneficial to environmental protection. A lot of our shipbuilding steel plates are produced by TMCP process.

Q690C carbon steel material, P355GH steel yield strength in different thickness has different values.Thickness 8-16mm: 355MPa min., ＞16-40mm: 345MPa min., ＞40-60mm: 335MPa min., ＞60-100mm: 315MPa min., ＞100-150mm: 295MPa min., ＞150-250mm: 280MPa min. The elongation minimum is 20%. P355GH plate under EN10028-2:2003 standard is a pressure vessel steel. It is always delivered in hot rolling, controlled rolling, normalizing.

Land transportation inquiry: (RMB fee) it is required to master the kilometers and towing price of major cities; packing price of each port area; customs clearance fee, commodity inspection fee, and animal and plant inspection fee standard. Key information to be clarified after accepting the consignation of the consignor (generally fax): shipping date, number of packages, box type, box quantity, gross weight and volume.

The high strength Q690C carbon steel material low alloy steel, which is shorten as HSLA steel, is one of our main products. We have professional team to serve you.
