KD36 hull ship structural steel plate,In recent years, in line with the development trend of iron and 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 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.
KD36 hull ship structural steel plate,S420M and S420ML are hot-rolled flat weldable fine-grained structural steel with a thickness less than 120mm. S420 steel is a non-alloy structural steel. The S420ML steel is composed of the following parts: S (structural steel); 420: the yield strength value of structural steel with a thickness less than 16mm: not less than 420; M represents his delivery status, that is, hot mechanical rolling; L: The impact when the temperature is not lower than -50 degrees is marked with a capital letter L.
KD36 hull ship structural steel plate,Pipeline steel can be divided into three types: high cold, high sulfur area and submarine laying. According to the development trend, service conditions, main failure forms and failure reasons of oil and gas pipelines, it is required that the pipeline steel not only has good mechanical properties, but also has negative temperature resistance, corrosion resistance, seawater resistance and hsscc resistance. These pipelines with bad working environment have long lines and are not easy to maintain, so they have strict quality requirements.
KD36 hull ship structural steel plate,Rolling steel is the process of pressing to change the shape of the ingot and billet between the rotating rolls The so-called steel rolling process is a combination of a series of steel rolling processes The entire rolling production process is always composed of the following basic processes: ① billet preparation:Including the cleaning of surface defects, the removal of surface scale and the pre-heat treatment of billets ② billet heating ③ steel rolling: it is the core of the entire rolling production process ④ Finishing,KD36 hull ship structural steel plate.
EN 10025-2 is standard for hot rolled products of structural steels. EN 10025-2 steel grades are S235JR, S235J0, S235J2 (S235 series); S275JR, S275J0, S275J2 (S275 series); S355JR, S355J0, S355J2, S355K2 (S355 series); and S450J0. The numbers 235, 275, 355, 450 indicates the min. yield strength for thickness ≤16mm. For example, when the thickness ≤16mm, the min. yield strength for S235 series steel is 235Mpa, S275 series steel is 275Mpa, S355 series steel is 355Mpa, and S450J0 steel is 450Mpa.
KD36 hull ship structural steel plate,Compared with other fast-moving consumer goods, steel consumption is obviously different, with a wide range of use and a long service life. Therefore, the quality and service of steel materials are particularly important. Service is always one of our top concerns, especially after-sales service. We have mature after-sales service team, and can help you solve problems professionally during application of the steel materials.KD36 hull ship structural steel plate
