Flame Cut Carbon Steel Plate Profiles — Factory Direct Supplier | Huaxia-Steel
Flame-cut (oxy-fuel) plate profiles are carbon steel plates cut to your drawing — rings, flanges, gussets, base plates, wear parts, and blanks — delivered ready for machining or welding. Cutting blanks from the mill saves your shop the cost of handling full plates, increases material utilization, and shortens your production cycle. Huaxia-Steel cuts plates from 6 to 300 mm thick using CNC oxy-fuel and plasma tables up to 12 m long, working with Q235B, Q345B, S355, A36, A572, NM400 wear plate, and 1045, with beveling and heat-treatment options.
Product Overview
We nest your parts on our plate inventory with software that maximizes utilization, then cut on CNC multi-torch oxy-fuel tables for heavy thickness (25–300 mm) or plasma for faster throughput at 6–50 mm. Edges can be supplied square or beveled (K, V, X preparation) for welding. For critical parts we offer normalizing or quench-and-temper after cutting to restore or enhance mechanical properties in the heat-affected zone. Every part is marked with heat number, part ID, and order reference for full traceability.

Typical Cutting Tolerances (ISO 9013, flame cutting)
| Thickness (mm) | Class 1 tolerance (mm) | Class 2 tolerance (mm) | Edge perpendicularity class 2 (mm) |
|---|---|---|---|
| 3 – 12 | ±0.5 | ±1.0 | 0.7 |
| >12 – 50 | ±1.0 | ±2.0 | 2.0 |
| >50 – 100 | ±1.5 | ±3.0 | 3.5 |
| >100 – 300 | ±2.5 | ±5.0 | 6.0 |
Thick flame-cut parts show a heat-affected zone and slight edge taper — if your drawing demands tighter tolerance or a machined surface, order parts with 3–5 mm machining allowance and we will pre-machine or supply oversize blanks.
Available Grades
Manufacturing Standards and Quality Control
Cutting follows ISO 9013 quality classes with ISO 9001 process control. Programs are verified against customer drawings before cutting; first-article checks are taken on every new job. Slag is removed, edges inspected for cracks (especially on wear and medium-carbon plates), and dimensional reports issued on request.
Applications
Packaging and Shipping
Parts are stacked on wooden or steel pallets with protective interleaving, bundled and strapped, with sharp edges capped or banded where needed. Heavy pieces are shipped loose with lifting lugs if specified. Each bundle carries a packing list cross-referenced to part IDs. We ship in containers, flat racks, or break-bulk with FOB, CFR, CIF, and DAP terms.
