The manufacturing process of p295gh material equivalent hot-rolled steel plates is simpler and cheaper than cold-rolled steel plates. However, foreign experience believes that the hot-rolling method is only suitable for the production of steel plates with a thickness of 1.6 mm or more, and it is uneconomical for thinner p295gh material equivalent steel plates. The surface quality and dimensional accuracy are not as good as cold-rolled steel plates. Hot-rolled steel plates on automobiles, in addition to frame longitudinal beams, cross beams and various brackets, also stamping wheel rims, roulettes, etc. that require a certain strength, and the surface is not stressed. Not too demanding shell cover, etc.

Q345R steel (16MnR) is a low-alloy high-strength steel. It is a special plate for pressure vessels with a yield strength of 340MPa min. Q345R plate has good comprehensive mechanical properties and technological properties. The phosphorus and sulfur contents are slightly lower than the low-alloy high-strength steel plate Q345 steel (16MnR). In addition to the increased tensile strength and elongation requirements compared to Q345B steel, p295gh material equivalent, the impact toughness is also required.

Indonesia's nickel pig iron production in 2021 is expected to be 900,000 tons, an increase of 4.7% year-on-year. In 2020, the nickel pig iron production for the whole year will be 860,484 tons. In addition, the production of high matte nickel is expected to decrease by 15% year-on-year to 78,000 tons, and the full-year output in 2020 will be 91,800 tons.
