Cold Rolled Grain-Oriented (CRGO) Electrical Steel is a high-purity silicon steel sheet subjected to precise multi-stage cold reduction and high-temperature secondary recrystallization annealing to develop a Goss texture ((110)[001] grain orientation). This alignment yields high magnetic saturation, high permeability, and low eddy current and hysteresis core losses along the rolling direction. Available in conventional, high-permeability (Hi-B), and laser-scribed grades such as 23M100, 27M120, 23HP85, and 30Z130, in thicknesses from 0.20 mm to 0.30 mm, with thin inorganic phosphate/magnesium silicate surface insulation (C-5). Sourced from specialized mills including Nippon Steel, POSCO, Baosteel, and JFE Steel.

Cold Rolled Non Grain-Oriented (CRNO) Electrical Steel is a specialized silicon-alloyed iron sheet product processed via cold rolling, continuous decarburization, and strand annealing to achieve an isotropic crystal structure. This non-directional orientation delivers uniform magnetic permeability and low core losses regardless of flux direction. Available in standard grades such as M45 (50C450), M47 (50C470), 35C300, […]

Hot Rolled Coil Pickled and Oiled (HRPO) is produced by running hot rolled coil through continuous hydrochloric acid pickling lines to dissolve mill scale, rust, and surface oxides, followed by an electrostatic application of rust-preventive oil. The resulting product combines the mechanical strength of hot rolled steel with a cleaner, scale-free surface that improves tool […]

Tin Mill Black Plate (TMBP) is an uncoated, high-purity, low-carbon cold rolled steel sheet engineered with tight thickness tolerances, high cleanliness, and uniform mechanical properties. Produced via tandem cold rolling, alkaline cleaning, and batch or continuous annealing, it serves as the base metal substrate for tinning, chromium plating, and specialized lacquering lines. Supplied in SR […]

Tinfree Steel (TFS), classified technically as Electrolytic Chromium Coated Steel (ECCS), is produced by cathode-plating a cold reduced steel substrate in a chromic acid bath to form a composite surface film of metallic chromium overlaid with hydrated chromium oxide. It offers high lacquer adhesion, thermal resistance up to 400°C, and resistance to sulfide staining, making […]
