The company adheres to the "variety, quality and efficiency" road. We have established a technology center, a brand cultivation management system and a quality control system. Now the company has formed an independent innovation system integrating shipbuilding use GL-D hull structural steel production, learning, research and marketing. Our company has passed ISO9001 quality management system certification and ISO10012 measurement management system certification.
SA516Gr45 (R-HIC) This type of steel plate is mainly used in the manufacture of equipment used in wet hydrogen sulfide environment, such as: liquefied petroleum gas desulfurization system, stable absorption system for catalytic cracking, condensation system of atmospheric and vacuum distillation tower, etc. The material shipbuilding use GL-D hull structural steel has the characteristics of high purity, low P, low S, good uniformity of structure and mechanical properties, resistance to hydrogen cracking and sulfide stress corrosion.
Special boiler steel is derived from carbon structural steel. The chemical composition of boiler steel is basically the same as that of high-quality carbon structural steel of the same level, but the shipbuilding use GL-D hull structural steel steel mechanical property requirements are more strict, especially for impact toughness. And the aging sensitivity is required to be small. The boiler steel should be deoxidized and the non-metallic inclusions should be removed during smelting. The structure should be uniform. The grain size should be controlled in 3-7 grades. The defects such as interlayer, shrinkage, porosity and porosity should be minimized.
There is an inherent difference between the cold forming properties of low-alloy high-strength steel and carbon structural steel. First of all, a certain amount of permanent deformation of low-alloy high-strength steel requires greater force than shipbuilding use GL-D hull structural steel, carbon structural steel of the same size. Second, when low-alloy high-strength steel is formed, a slightly larger allowable amount for springback should be given. According to experience, unless the low-alloy high-strength steel is processed to control the shape of inclusions, it is necessary to use a larger bending radius than carbon structural steel during cold forming.
SS400 is a low carbon steel with no specified carbon content. According to its mechanical properties, it is similar to shipbuilding use GL-D hull structural steel ASTM A36, which is widely used in engineering and industrial applications. The cost of JIS SS400 steel angle steel structure is low, and it has good performance in major projects. SS400 angle steel description:Item: SS400 angle steel. shipbuilding use GL-D hull structural steel Standard: JIS G3101-2004. Technology: hot rolled. Type: equal & unequal. Surface: black or galvanized. Length: 6 m, 9 m, 12 m or per your request. Equal angle: Size: 20 × 20 mm to 200 × 200 mm. Thickness: 3 to 20 mm. Length: 6 m, 9 m, 12 m or per your request. Unequal angle: Size: 30 × 20 mm to 250 × 90 mm. shipbuilding use GL-D hull structural steel Thickness: 3 to 10 mm. Length: 6 m, 9 m, 12 m or per your request.
When providing technical services on site, the after-sales personnel shall strictly abide by the safety rules and regulations of the construction site, consciously take safety protection measures (such as wearing safety helmet when entering the construction site), accept the supervision and management of the site; without permission on the construction site, they shall not dismantle, smear or damage any goods; the commissioning of contract goods shall be carried out under the supervision of the site supervisor If necessary, it shall be approved by the site supervisor or the person in charge of the project department.
