Recently, HBIS Group's Han Steel's domestically launched C2101NSSL, a corrosion-resistant cold-rolled hot-formed steel with a tensile strength of 1500MPa and an extremely thin specification of 1.0mm, was delivered to a well-known company for use. It has excellent corrosion resistance and comprehensive performance that fully meets customer needs. It will be used in the manufacturing of special square and round tubes such as large commercial carriage bodies and prefabricated buildings. It will be used in the manufacture of special square and round tubes for large commercial vehicle bodies, prefabricated buildings, etc. This product is the first customized research and development based on client needs, filling the gap of domestic cold-rolled hot-formed steel products without a corrosion-resistant series, helping customers extend the service life and lighten key parts.

Corrosion-resistant cold-rolled and hot-formed steel is a brand-new product and a cutting-edge steel material in China. While it has the high strength and toughness, good forming properties and good welding properties of traditional cold-rolled and hot-formed steel, it also has excellent corrosion resistance. It meets the requirements of higher strength, longer life and corrosion resistance of core parts such as automobile bodies, prefabricated buildings and agricultural machinery during service, which helps to extend the service life of parts and reduce weight and has broad market prospects.

Han Steel is deeply close to the market and customers, and continues to make efforts to meet the needs of the client, continuously increase the research and development of advanced steel materials, strive to create domestic first-time products that replace imported products, comprehensively improve the ability to catch up with customers, satisfy customers, and connect customers, and truly form differentiated competitiveness. The Han Steel Technology Center and HBIS Automotive Plate have strengthened customer visits and docking. According to the special requirements of customers for materials, they have innovatively designed product composition systems and formulated process production plans, and customized and developed corrosion-resistant cold-rolled hot-formed steel. Han Steel technicians use clean steel smelting technology to change the characteristics of inclusions; innovatively adopt the "three-stage" heat treatment process and double flattening process to strengthen the control of key process links such as slow cooling of ingots, low-temperature heating of hot rolling, and cold rolling reduction rate, and successfully overcome the industry difficulties in thin-gauge cold-rolled hot-formed steel forming control. After the product is delivered, it also provides customers with forming, welding, and heat treatment process solutions, and conducts full-process tracking and guidance to ensure that the product passes the processing trial smoothly and is recognized by customers.
