Welcome to BBN High Strength Steels Factory
The company initially focus on providing high-quality steel products to serve for China's rapid infrastructure development. Our company vision is to be the best service provider for iron & steel 1.8933 steel equivalent products globally. To be an innovative business partner for our customers we aim to include sustainability in every aspect of our 1.8933 steel equivalent business. We also provide third-party inspection and approval services and inventory management for our customers.
The types of carbon steel are basically as the following: 1.8933 steel equivalent, Carbon structural steel, which is mainly used in various projects. High-quality carbon structural steel, whose main purpose is for important parts. Carbon tool steel, which is mainly used to make various small tools. Cast carbon steel parts for general engineering, which are mainly used for complex parts that are difficult to form by forging and other methods and require high mechanical properties.
The main advantage of 20CrMo alloy steel plate is reflected in its various physical and chemical properties. For 20CrMo alloy plate, the main component is alloy, and the physical and chemical properties of alloy 1.8933 steel equivalent are generally, a single metal is better, and its performance is stronger. The main features of 20CrMo alloy steel plate are high precision, rigidity, high temperature and high pressure resistance, not easy to corrode and other characteristics.
Expression method of pressure coefficient of seamless steel pipe: pressure P < 7MPa coefficient S-8 7 < 1.8933 steel equivalent steel pipe pressure P < 17.5, coefficient 5-6 pressure P > 17.5, coefficient S-4 seamless pipe production and manufacturing: tube blank -- Inspection -- peeling -- Inspection -- Heating -- perforation -- pickling -- grinding -- lubrication and air drying -- welding head -- cold drawing -- solution treatment -- pickling -- pickling and passivation -- Inspection -- cold rolling -- degreasing -- air drying -- internal polishing -- one external polishing -- Inspection -- identification of finished 1.8933 steel equivalent product packaging.
EN 10025-2 is standard for hot rolled products of structural steels. EN 10025-2 steel grades are 1.8933 steel equivalent, 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.
The 365 day service system is implemented, and the business, loading and delivery are handled as usual in holidays and festivals. Actively help users solve difficulties. When users encounter difficulties in handling business, they should actively coordinate with the external solution; if they need to solve the problems internally, they should solve them in a timely manner without prevarication and wrangling. In line with the 1.8933 steel equivalent principle of "fairness, justice and timeliness", coordinate with relevant departments and deal with all kinds of objections in a timely manner.
