30CrMnSiA belongs to the alloy structural steel plate, also belongs to the military steel, 30CrMnSiA not only has very high strength but also has a certain toughness, wear resistance, fatigue resistance, corrosion resistance, impact resistance and easy to process molding properties. Generally used in guns and light weapons, missiles, armored vehicles, aviation equipment, military spare parts, aerospace equipment and other aspects of a very wide range.
30CrMnSiA executive standard: the implementation of GB 3531-2014 standard.
30CrMnSiA steel plate delivery status: normalized.
According to the requirements of the demand side, 30CrMnSiA steel plate can also be normalized + tempered, quenched + tempered state delivery, thickness flaw detection can be done 1 probe, 2 probe, 3 probe, different delivery status will directly affect the composition of the steel plate performance and use, so in the selection of the delivery state should be well harmonized with the use of the current situation.
30CrMnSiA steel plate size, shape, weight and allowable deviation regulations:
1, the size, shape and allowable deviation of the steel plate should be consistent with the provisions of GB/T709.
2, Thickness deviation should be in accordance with GB/T709 class B deviation requirements, according to the requirements of the demand side, can also be delivered according to GB/T709 class C deviation.
3, Theoretical weight of steel plate is delivered, and the thickness used for theoretical weighting is the arithmetic average of the maximum thickness and minimum thickness allowed for steel plate. The density of steel is 7.85g/m³.
