Nanjing Huishang Technology Co., Ltd. is one of the leading manufacturers professional in manufacturing forged steel round bars, alloy steel round bars, forged square steel, forged flat steel, forged shafts, hot rolled steel, tools and die steel. We have 800-2500 ton quick forging equipment for producing high quality products of carbon steel and alloy steel, such as S10C-S60C, S355J2G3, SCM420-440, SCM415, CK45, AISI 4140, SNCM420 and SNCM439. The diameters are ranging from 100mm to 1000mm for round bars and 120-1200mm for flat and square steel, with length up to 15m. Our products cover Japanese standard, Chinese standard, German standard, American standard and other standards.
The surface can be black, rough machined, bright and anti-rust according to customers' requirements. The forged products can be normalized, annealed, quenched and tempered and surface quenched.
The technical process of raw material - steel ingot is EF+LF+VD to assure its inside quality, so the forged steel bars made from it will meet UT&MT testing specifications, such as SEP1921-84 C/c, D/d, E/e; JIS G 0587 CLASS 2, EN10228 CLASS 2 and others.
