Raw Material Control

I. Raw Material Control for Cast Products:

cl 1.1 Material Selection: Large-sized channel steel, angle steel, scrap steel, 42CrMo alloy steel, and iron filings are used as raw materials. These materials undergo rigorous inspection and strict quality control.
1.2 Depending on the requirements of each product, high‑carbon ferrochrome, low‑carbon ferrochrome, ferromanganese, copper, ferromolybdenum, ferronickel, ferrotitanium, rare earth alloys, and other alloying elements are added as appropriate; the actual content of each alloy is re‑verified in our laboratory.
1.3 Materials shall be stacked and managed according to their material categories, with labeled tags indicating the respective categories.

 

II. Raw Material Control for Forged Products:

2.1 The raw materials used for forging steel balls and wear-resistant steel rods are round bars of various diameters.

2.2 We select Chinese special steel manufacturers as our qualified suppliers, whose raw materials are of consistently high quality.

2.3 Upon arrival at the factory, round steel is subject to re‑inspection by our company, covering both its chemical composition and mechanical properties. Only raw materials that pass laboratory testing are permitted to enter the site.

2.4 Store and manage raw materials by material type, with clearly labeled tags.
