High Carbon & Alloys Steel Strips
Product Process Overview
High Carbon & Alloy Steel Strips
Precision engineered high carbon and alloy steel strips produced through advanced thermal treatment, cold rolling, slitting, and finishing lines to achieve superior hardness, strength, and dimensional accuracy.
Bell Annealing
Heat treatment process used to relieve internal stresses caused by work hardening. The material is heated to a controlled temperature, soaked, and slowly cooled to refine grain structure and improve ductility before cold rolling.
20-Hi Cold Rolling Mill
Advanced cluster mill (Sendzimir type) designed for ultra-high precision rolling of hard metals. Ensures exceptional dimensional accuracy, surface quality, and capability for ultra-thin gauges.
4-Hi Cold Rolling Mill
Backbone of high-volume steel processing, delivering consistent thickness control, superior surface finish, and efficient production for industrial-grade applications.
Slitting Line
Precision shearing process used to cut wide coils into narrow strips as per customer requirements. Ensures uniform width, smooth edges, and high productivity.
Hardening & Tempering (H&T) Line
Steel is heated above recrystallization temperature to form austenite, quenched to form martensite, and then tempered to achieve desired hardness, toughness, and dimensional stability.
Edge Profiling Line
Machining process using carbide tools to produce round or square edges, enhancing product safety, usability, and performance in downstream applications.
Strip Grinding Line
Removes surface scale and black oxide layers using abrasive belts, producing smooth and clean metallic surfaces.
Polishing Line
Super finishing process using mops and abrasives to achieve high surface refinement, especially suitable for thin and precision strips.
Color Tempering Line (Blue Annealing)
Advanced thermal process using molten salt bath to create controlled oxidation layers, producing temper colors such as grey, blue, and bronze through thin film interference. Ensures uniform heating and decorative surface finish.
