Q345R Chinese Steel Grade

　　Q345R steel is a Chinese standardized alloy steels with specified elevated temperature properties, and is used for manufacturing pressure vessels and boilers.

　　Q345R steel properties: Q345R grade is the yield strength of steel for 340MPa special plates for pressure vessels, it has good mechanical properties and process performance. Phosphorus, sulfur content slightly below the low alloy high strength steel Q345 (16Mn) steel, with the exception of tensile strength, elongation than Q345 (16Mn) steel increased, but also require the toughness. It is currently the most widely used, and the largest amount of special steel for pressure vessels.

　　Q345R Steel Standard

　　G713-2014 specifies steel plates for boiles and pressure vessels, steel flat products for pressure purposes.

　　Technical delivery conditions: Hot rolling, control rolling or normalizing

　　Q345R Steel Plates Specification

　　Width: 1220-4200mm

　　Length: 5000-18000mm

　　Notes: coil thickness ≤ 25mm

　　Testing of Q345R Steel Plates

　　The testing of the Q345R plates is done very much effectively by the team of experts that are having all good knowledge and skills. The tests are conducted for the purpose of assurance of quality of plates supplying. It includes positive material identification test, pitting resistance test, hardness test, flattening/flaring test, chemical test, macro/micro test, mechanical test and intergranular corrosion test.

　　Inspection In The Industry

　　On a fixed interval of time the industry is inviting a thorough inspection in order to make sure that the production of the plates is done very well. The inspection is done by the legally certified and high knowledgeable third party inspection team. On the basis of few parameters the inspection takes places so the effective inspection can be conducted. According to the condition of the production the industry is giving the report to the producers and they as per the report are enhancing production quality.

　　Delivering

　　The suppliers are assuring timely and good condition of the Q345R Plates.
