3. Manufacturing Process: manganese steel plate & High Chrome Hammer Head
1 Raw Material Selection: Premium iron ore, ferromanganese alloys, coke, and silicon are sourced, analyzed by spectrometry for compliance with standards (ISO 9001, ASTM A128).
⬇️
2 Melting & Alloying: Induction or electric arc furnaces melt raw materials, with precision alloy additions (silico manganese, silicon manganese) to achieve targeted compositions.
⬇️
3 Forming / Casting: Steel is cast as slabs (for plates) or into high-precision molds (for hammer heads). Controlled cooling prevents undesired carbide formation.
⬇️
4 Hot Rolling or Forging: Plates are rolled to precise thickness (4–60mm) on reversing mills. Hammer heads are forged or precision cast for optimal grain alignment.
⬇️
5 Heat Treatment: Solution annealing at ~1050°C, followed by rapid water quenching, enhances austenitic structure for maximum wear resistance.
⬇️
6 CNC Machining & Finishing: Computer-controlled machining achieves tight tolerances, custom holes, or beveled edges.
⬇️
7 Quality Inspection: Destructive and non-destructive tests as per ISO 6508 (hardness), ISO 6892-1 (tensile), ultrasonic, and X-ray flaw detection.
⬇️
8 Packing & Logistics: Plates or products are corrosion-wrapped, labeled, and shipped globally, certified with mill test certificates.
