Agree a single material and delivery condition before selecting steel coil for downstream fabrication.
Route and hardness
The title combines hot rolled, black annealed and cold rolled conditions with high hardness wording. The detail identifies cold rolled coil and mid hard material, so confirm the actual route, heat treatment and hardness test requirements instead of combining these descriptions.
Grade and dimensions
The detailed grades differ from parts of the title list. Select one actual designation, thickness and usable width, then agree customer length and the slightly oiled, skin pass surface condition for the order.
- Actual material designation
- Rolling and heat treatment
- Hardness inspection basis
- Thickness and usable width
- Oiling and surface criteria
Processing acceptance
Building material wording supplies no measured forming or mechanical result. Request actual material records and process acceptance; no universal grade equivalence, black finish or high hardness performance is established.
