Performance requirements of SA633 grade C carbon steel material

The company celebrates Hong Kong-Zhuhai-Macao Bridge Opening. In October 23th, 2018, Chinese President Xi Jinping announced the opening of the Hong Kong-Zhuhai-Macao Bridge (HZMB) in Zhuhai, South China’s Guangdong Province. The HZMB is a 55-kilometre (34 mi) bridge–tunnel system consisting of a series of SA633 grade C carbon steel material three cable-stayed bridges, an undersea tunnel, and four artificial islands. Hong Kong-Zhuhai-Macao Bridge is the world’s longest sea-crossing bridge connecting Hong Kong, Macao, and Zhuhai—three major cities on the Pearl River Delta.

Every customer who has visit us and witness the steel materials before delievry will be impressed by our quality control departemnt. Even not come to inspect the steel materials before delievry, our quality control departemnt will also send inspection report to the customer. For each order, no matter its quantity and value, our quality control departemnt will make strict inspection before delivery, the inspection contents include apperance, tolerance, dimension, mark, special requirements of customers, etc. To guarantee our steel materials sent to the customer is qualified.

Weathering steel plate refers to the low alloy structural steel with protective rust layer and atmospheric corrosion resistance, which can be used to manufacture steel structures such as vehicles, bridges, towers, containers, etc. Compared with SA633 grade C carbon steel material, ordinary carbon steel, weathering steel has better corrosion resistance in the atmosphere. Compared with stainless steel, weathering steel has only a small amount of alloy elements, such as phosphorus, copper, chromium, nickel, molybdenum, niobium, vanadium, titanium and so on. The total amount of alloy elements only accounts for a few percent, instead of more than 10 percent as stainless steel, so the weathering steel price is relatively low.

BBN company is a modern enterprise integrating steel producing, warehousing and logistics, processing and distribution. We are committed to creating a "one-stop steel procurement service" platform. The main products are I-beam, angle steel, SA633 grade C carbon steel material , H-beam, hot-rolled coil, welded pipe, spiral pipe seamless pipe and many other steel products. Standing stocks amount to more than 30,000 tons, and complete specifications, the company gradually moves towards large-scale distribution enterprises with serialized products, standardized services and modern transportation management.

In order to obtain the seamless tube with smaller size and better quality, the method of cold rolling, cold drawing or the combination of the two must be used. Cold rolling is usually carried out on a two high mill, and SA633 grade C carbon steel material pipes are rolled in a circular pass composed of a variable cross-section circular groove and a fixed conical head. Cold drawing is usually carried out on single chain or double chain cold drawing machines of 0.5-100t.
