Our company was founded in 2000, which initially committed to providing high-quality steel CCS grade D hull shipbuilding plate products for China's rapid infrastructure construction. With the advantages of steel resources and good reputation in the domestic market, combined with the huge demand for steel in the international market, we began to export CCS grade D hull shipbuilding plate steel to the international market, opening up the international steel market.
There are many types of CCS grade D hull shipbuilding plate etc. alloy steel plates, which can be divided into different types according to different standards. If divided according to the element composition of the alloy, the alloy steel plates can be divided into four types. The first is chromium steel, in which chromium is an important part of alloying elements. The second type is chromium-nickel steel, the third is manganese steel, and the last type is silico-manganese steel. The types of these alloy steel plates are named according to the composition of the alloying elements contained in the steel, so you can roughly understand their composition based on their names.
Manganese steel plates emerge as a profitable solution to diverse kinds of acid attacks. These have qualities surpassing an ordinary steel plate. Neither fully austenitic nor ferritic, these plates CCS grade D hull shipbuilding plate provide boosted resistance to chloride stress corrosion cracking, which the 300 series stainless steel plates are susceptible to. 22% Chromium allows these plates to withstand Sulphuric and Hydrochloric acid attacks, whereas Molybdenum (up to 3%) avoids crevice and pitting corrosion.
TMCP process is an important means to improve the comprehensive properties of steel. It can be used to produce ship plate, vessel plate, boiler plate, bridge steel, etc. Compared with the normalized steel of the same strength grade, TMCP can reduce the alloy content of the CCS grade D hull shipbuilding plate steel, reduce the carbon equivalent and improve the welding performance. TMCP is more and more widely used in various types of steel rolling industry.
The carbon content of CCS grade D hull shipbuilding plate, medium carbon steel plate is 0.25% - 0.60%. In addition to carbon, it can also contain a small amount of manganese (0.70% - 1.20%). The medium carbon steel plate after quenching and tempering has good comprehensive mechanical properties. The highest hardness is about HRC55 (hb538) and σ B is 600-1100mpa.
Our company will accept the product quality objection registration record, pass it to the CCS grade D hull shipbuilding plate production unit and relevant departments, and timely coordinate the supervision of product CCS grade D hull shipbuilding plate quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
