Industrial Background

Practical foundation

Aobo Steel’s tool steel experience is closely connected with Huangshi’s local forging and mold material supply network. Our background helps us understand the practical details behind tool steel supply, including forging quality, annealed condition, internal soundness, machining allowance, surface condition, hardness condition, and inspection control.

For grades such as D2, D3, H13, H11, Cr12, Cr12MoV, and 9Cr18Mo, buyers need more than a grade name on paper. The material must match the agreed chemical composition, size, delivery condition, inspection requirement, and documentation before shipment. Aobo Steel focuses on these practical supply details so customers can receive material that is suitable for machining, stocking, resale, and later heat treatment.

Quality Control Before Shipment

Inspection focus

Quality control must happen before the material enters the buyer’s warehouse, machining process, or heat treatment process. Aobo Steel focuses on inspection items that matter to distributors, stockists, importers, and industrial users.

UT Inspection

Ultrasonic testing helps check internal soundness before shipment according to agreed requirements.

Hardness Check

Hardness inspection helps confirm supplied condition, especially annealed condition for downstream machining.

Chemical Composition

Composition checking supports grade confirmation and reduces the risk of material mismatch.
