Import Alloy Steel Rolls — Buy in wholesale FOB from Supplier in China

Alloy Steel Rolls from Tianjin Hiking Trading Co., Ltd are manufactured from chromium-molybdenum and nickel-chromium-molybdenum alloy steel grades, heat-treated to develop wear-resistance and toughness properties for rolling mill applications. The rolls serve as backup and roughing rolls for plate and strip mills, breakdown rolls for rail beam and universal section mills, and descaling, roughing, backup, and vertical rolls for strip mills. Their metallurgical design targets the repeated thermal and mechanical stress cycles inherent in hot and cold rolling operations.

The material composition centres on alloy steel enhanced with chromium for hardenability and oxidation resistance, molybdenum for elevated-temperature strength and creep resistance, and nickel where specified for improved toughness at lower temperatures. Heat treatment, which may include normalising, quenching, and tempering cycles, develops a surface hardness profile suitable for contact with hot steel slabs and billets. Typical hardness ranges for such rolls fall between 50 and 80 HSD (Shore hardness), though the exact value depends on the specific roll position and customer rolling schedule. Core mechanical properties typically include minimum tensile strength of 800-1000 MPa for forged alloy steel rolls, with elongation and impact values varying by grade and heat treatment route.

Primary buyers include integrated steel mills, mini-mills, and specialised rolling equipment manufacturers servicing the automotive sheet, long product, and rail sectors. The rolls are capital spares with service lives measured in thousands of rolling hours, and buyers typically negotiate specifications against mill-specific roll pass designs. Trade terms for alloy steel rolls of this scale commonly involve FOB Tianjin or CFR main port, with manufacturing lead times that can extend to several months given the forging, heat treatment, and rough-machining stages. Buyers should confirm roll body diameter, total length, neck dimensions, and bore specifications to match existing mill housings and chocks.

Tianjin Hiking Trading Co., Ltd is located at No. 903, Chuangzhi Building, Zhongxin Eco-City, Binhai New Area, Tianjin, 300480, China. The company operates under a harbor trust tier on the platform, with a response rate of 0.00 percent and no recorded average response hours. The listing presents the company as a trading entity focused on alloy steel rolls and related steel products for industrial mill applications.

The profile does not disclose manufacturing ownership, factory certifications, years in operation, annual turnover, employee count, or specific client references. Buyers should verify whether Tianjin Hiking Trading Co., Ltd operates as a pure trader or maintains mill partnerships for roll production and refurbishment, and whether it can provide material certificates, heat treatment records, and dimensional inspection reports for each roll supply.
