Based on the main normalized CCS grade E bulk vessels steel business of iron and steel, we are committed to producing high-quality, green and efficient steel products. The main steel products are medium and heavy plate, hot rolled coil, section steel, steel tube, etc., which are widely used in automobile, oil, railway, bridge, construction, electricity, transportation, machinery, shipbuilding and other important fields. Our steel normalized CCS grade E bulk vessels steel products are exported to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.
BBN Steel Company adheres to the marketing concept of "first-class technology, first-class steel quality, and first-class logistics services". It is our goal to build high-quality carbon steel normalized CCS grade E bulk vessels steel, alloy steel plates and high-strength structural steel plate international-class boutique bases. Our logistic team will make customs clearance documents, track products production process, and update shipping information for customers. Creating value for customers is our pursuit.
Quenching is a common heat treatment process. It is the metal heat treatment process in which the normalized CCS grade E bulk vessels steel metal workpiece is heated to a proper temperature and kept for a period of time, then immersed in the quenching medium for rapid cooling. Quenching can improve the strength and hardness of steel in a large range, and adjust the coordination between normalized CCS grade E bulk vessels steel strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.
BBN steel had provided Grind plates for more than 15 years for widely applied in equipment, Engineer machinery etc. In 2018, one of our India customer visit our normalized CCS grade E bulk vessels steel office and work shop to discuss Q235B Grind plate technical request, they have strict surface and thickness tolerance, and they also request UT and MT for testing. As a result, they purchase normalized CCS grade E bulk vessels steel 179 tons as trial order for first cooperation. And have good comment on our quality. Till now, we keep exporting around 100 tons per month as regularly.
20 # material is a high-quality low-carbon carbon steel, cold-extruded, carburized and hardened steel. normalized CCS grade E bulk vessels steel, 20 # material has low strength, good toughness, plasticity and good weldability. Chemical composition of 20 # round steel bar: C: 0.17 ~ 0.23, Si: 0.17 ~ 0.37, Mn: 0.35 ~ 0.65, S: ≤0.035, P: ≤0.035, Cr: ≤0.25, Ni: ≤0.30, Cu: ≤0.25. 20# carbon steel mechanical properties: Shear strength 275 ~ 392MPa, Tensile strength is 253 ~ 500MPa, elongation min. 25%.
