Manganese plate


Usually said manganese plate is a high strength low alloy structural steels, 16Mn ( Q345 ) or 16Mn ( Q345 ), the material weldability, can use a variety of welding method.

Plate usually fingerboard thickness in the range of 4mm-60mm steel plate.

16Mn is a veteran, now is a grade Q345.

The grade of Q345 A, B, C, D, E five.

16Mn (Ⅰ,Ⅱ,Ⅲ) are 1, 2, 3 forging.

16MnR is generally the main material of pressure vessel, R refers to steel, which is steel plate for pressure vessel materials.

16MnD D is low temperature steel.

16MnR material welding characteristics, usually without preheating is not required and slow cooling, but the thickness of greater than 30 preheating 100-150 degrees, usually with J507 can weld toughness, if any better, can also be recommended by J507RH.

J507 is electrode

J507RH and J507, from the mechanical performance of the same, only the coating composition is different, J507RH is a super low hydrogen electrode, low alloy, high toughness.

The 14 manganese plate is what material.

High manganese steel. High manganese steel have two biggest features: First, the greater the external shocks of its own higher surface abrasion resistance; With the gradual wear of the surface-hardened layer, the new work hardening layer will continuously formed.
Widely used in metallurgy, mining, building materials, railway, electricity, coal, cement and other mechanical equipment.
If the grade is 14MnVTiRE alloy structural steel. Steel sign at the beginning of the two-digit representation of the carbon content of the steel, said that the average carbon content of the very few behind the Mn indicates high manganese content. General Steel 0.30-0.50% manganese. Even when adding more than 0.70% carbon steel manganese steel. ”
