16Mo3 composition surface cracks refer to the linear cracks on the surface of 16mo3 composition, which should generally be the same as the forging or rolling direction. Formation reason: it is mainly due to the hairline, hot crack and cold crack caused by surface over burning, decarburization, looseness, deformation and excessive internal stress during processing (forging, rolling, heat treatment, quenching and tempering), as well as the high content of sulfur and phosphorus impurities on the surface. Inspection method: 16mo3 composition surface cracks can be detected by naked eye observation, acid pickling, magnetic particle inspection, coloring inspection and metallographic method.

Affected by the weak futures performance and weak spot follow-up, the steel billet price is temporarily stable. The overall growth trend of China's 16mo3 composition is slowing down, and the demand in the north is lower than that in the south. Under the background of economic recovery, the demand toughness still exists, the resource inventory is tight, and the actual willingness of the spot merchants to let the price is not obvious. The price of 16mo3 composition is expected to be adjusted and operated stably.

16mo3 composition, SA387Gr22CL2 low alloy high strength steel with high purity and good quality is used for high temperature boilers or other high temperature pressure vessels. Chemical composition of SA387Gr22CL2 steel: C: 0.05 - 0.15; Mn ≤ 0.10; Si: 0.30 - 0.60; P ≤ 0.010; S ≤ 0.005; Cr: 2.00 - 2.50; V ≤ 0.010; Mo: 0.90 - 1.10; Nb ≤ 0.010; Al ≤ 0.06; Ni ≤ 0.20; Cu ≤ 0.15; Ti ≤ 0.010.

In recent years, in line with the development trend of iron and 16mo3 composition steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which 16mo3 composition are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.
