Australia 350 just corresponds to what material in China

This is the Australian standard AS NZS 3678

Requires carbon equivalent of structural steel, for strength and elongation.

There are high requirements.

Also, carbon equivalent.

It seems that there is production in China.

The silicon content of C250 is, whereas the silicon content of Q235 is< =, the silicon content exceeds the standard, and it cannot be fully corresponded.

Australia 350 just corresponds to the domestic 00ni18co13mo4tial 022ni18co13mo4tial material.

Maraging steel is an ultra-high-strength steel based on carbon-free or ultra-low-carbon fe-Ni martensitic and precipitated and hardened by intermetallic compounds after aging treatment. The strength of this type of steel does not come from carbon, but from the precipitation of intermetallic compounds.

Among them, 00Ni18CO8Mo5TIAL, that is, 18Ni (250), has been included in China's national standard GB T 1299-2014 "Tool and Die Steel".

Performance characteristics: Shanghai Bingzheng Industrial **** 18ni steel solid solution after the formation of ultra-low carbon martensite, hardness of 28 30hrc, after aging treatment, due to the dissolution and precipitation of various types of intermetallic compounds to obtain aging hardening, the hardness can rise to the outstanding characteristics of steel is that under the conditions of ultra-high strength and high hardness, it still has good toughness and high fracture toughness. At the same time, this kind of steel has no cold work hardening, small aging heat treatment deformation, good welding performance, and the surface can also be nitrided.

Shanghai Bingzheng Industrial ****18ni martensitic aging steel has high strength and hardness (ultra-high tensile strength, surface hardness 50 54HRC), both good toughness and plasticity, is a key material for the manufacture of aerospace and defense industry equipment, widely used in aviation, aerospace, precision molds and other industrial fields, is currently widely used at home and abroad to manufacture rocket engine shells, missile shells, uranium isotope centrifugal separator high-speed drum and other high-precision load-bearing parts of the material.

The number is to represent that the yield strength must be greater than this number, and there are many materials to choose from, and the key is the thickness.

18 nickel martensitic aging steel, this grade is also used in China, 300 indicates yield strength, the unit KPSI (thousand pounds per square inch,), converted into the national standard at about 2000MPa.
