Why Jiyuan
One city, the full process chain for heavy steel parts
Jiyuan, in Henan province, is one of China's special steel and heavy machining clusters: steelmaking, forging, heat treatment and precision machining operate side by side. Core Steel Worksis the export interface to that base — we qualify the workshop, own the inspection scope, and handle documentation and logistics so overseas buyers get factory economics with exporter accountability.
What the base does in-house
Special steel
Local production of alloy and tool steels — the raw material starts minutes from the forge, not weeks away.
Open-die forging
Press capacity for shafts, mold bodies and blanks up to 40 t, with controlled reduction ratios.
Heat treatment
Normalizing, quench & temper, stress relief, induction hardening — with charted cycles on every certificate.
Deep-hole machining
BTA boring and honing for mold bores, cylinders and hollow shafts, L/D beyond 10:1.
Heavy machining
Lathes, boring mills and grinders sized for rolls, molds and mill housings.
Export base
Long-standing export production for oilfield, foundry and metallurgical customers worldwide.
A sourcing partner, not a trading blind box
Every RFQ is reviewed by engineers before it is priced: material grade, tolerances, NDT scope and packing are confirmed in writing. Orders are placed with the qualified workshop for that specific process — a mold body goes to a deep-hole line, a work roll to a roll shop — and inspection is held against the agreed plan.
You always know what you are getting: the drawing revision, the certificate package, the inspection reports and the packing list are traceable on every shipment.
