The company attaches great importance to systematic management, and has passed the 1.8940 steel ISO9001 quality management system, ISO14001 environmental management system, OHSAS18001 occupational health and safety management system, and ISO 9001: 2008 certification. Insist on 1.8940 steel quality and promote brand development. The company's physical and chemical testing equipment is fully equipped and the quality management operation is standardized. Since 2002, the national, provincial, and municipal product quality inspection random inspection pass rates are all 100%.

Q345DR steel is a pressure vessel special plate with yield strength of 340MPa grade. It has good comprehensive mechanical properties and process performance. Phosphorus, sulfur content than ordinary 16Mn steel, in addition to tensile strength, elongation requirements than ordinary 16Mn steel has been improved, but also required to ensure impact toughness. 1.8940 steel was China's most widely used, the largest amount of pressure vessel special steel.

Specification range of available steel 1.8940 steel: thickness ≤ 650mm, width ≤ 4500mm, length ≤ 18000mm. Larger specifications of steel plates are also available as required. Our steel plates 1.8940 steel can be supplied according to Chinese standard, American Standard AISI / ASME / ASTM, Japanese JIS, German standard DIN, French NF, British BS, European EN, international ISO and other standards. Heat treatment process: controlled rolling, normalizing, tempering, normalizing plus tempering, quenching and tempering, etc.

The acicular ferrite pipeline steel can inhibit the formation of polygonal ferrite, promote the acicular ferrite transformation, and improve the precipitation strengthening effect of carbon and niobium nitride by adding molybdenum to reduce the transformation temperature of polygonal ferrite, so as to improve the strength of steel and reduce the ductile brittle transition temperature. The 1.8940 steel, tempered sorbite pipeline steel adopts the heat treatment process of quenching and tempering. The tempered sorbite structure is formed to meet the comprehensive requirements of thick wall, high strength and sufficient toughness.
