Choosing Abrex 450 (NSSMC, Japan Make)
Abrex 450 (NSSMC, Japan Make) is in the 450 HBW hardness class. Higher hardness generally lasts longer against sliding abrasion but is harder to bend, cut and weld; where parts also take heavy impact, a tougher, lower class can last longer.
| Class | Nominal hardness | Typical use | Forming and welding |
|---|---|---|---|
| 400 | About 400 HBW | Dumper bodies, chutes, hoppers, screens | Cold bending and welding with normal care |
| 450 (this page) | About 450 HBW | Buckets, liners and heavier wear parts | Larger bending radii; preheat thicker sections |
| 500 | About 500 HBW | Cutting edges, crusher and severe-abrasion liners | Limited forming; strict cutting and welding procedures |
Other Abrex classes
Brands of the same class are comparable, not identical; confirm any substitution with the end user. See all brands on Wear Resistant Plates.
Applications for Abrex 450 (NSSMC, Japan Make)
Typical uses include abrasion-exposed parts that also need good weldability and formability. Tell us the abrasive material, impact level and the life of the current part so the right class can be quoted.
Cutting, Fabrication and Welding
Champak Industries describes full and part plate/profile supply and a plasma-cutting service. Thermal cutting softens a narrow edge zone, and thick or hard plate may need preheat before cutting. Weld with low-hydrogen consumables and the mill’s preheat and interpass limits; do not heat the plate above the mill’s tempering limit. See AR Plates for bending and drilling guidance.
Testing, Inspection Documents and Traceability
| Requirement | What to identify in the order |
|---|---|
| Mill test certificate | EN 10204 3.1 showing brand and grade, heat number, chemistry and hardness |
| Impact test | Charpy test temperature and minimum energy, if required |
| Traceability | Heat and plate number transferred to cut pieces |

Abrex 450 (NSSMC, Japan Make): Frequently Asked Questions
01What is Abrex 450 (NSSMC, Japan Make)?
Abrex 450 (NSSMC, Japan Make) is wear-resistant steel plate in the 450 Brinell hardness class, made by Nippon Steel (formerly NSSMC). It is used where abrasion shortens the life of ordinary structural steel.
02What hardness does Abrex 450 (NSSMC, Japan Make) have?
This page gives 410 – 490 HBW. Hardness ranges can fall with thickness, so confirm the guaranteed range for your thickness on the mill’s datasheet.
03Who makes this plate?
Abrex plate is made by Nippon Steel (formerly NSSMC). The mill and heat number are shown on the mill test certificate.
04Which thicknesses are listed?
This page lists 6 (4.5) – 50 mm. Availability for each size is confirmed at quotation.
05Is Abrex 450 (NSSMC, Japan Make) the same as other 450 HBW wear plates?
Wear plates of the same hardness class are comparable, not identical. Chemistry, toughness and processing advice differ by mill, so confirm any substitution with the end user.
06Can Abrex 450 (NSSMC, Japan Make) be bent?
Yes, by cold bending with larger punch radii and die openings than mild steel. Follow the mill’s minimum radius for the thickness and rolling direction.
07Can Abrex 450 (NSSMC, Japan Make) be welded?
Yes, with low-hydrogen consumables and the preheat and interpass temperatures the mill gives for the grade and combined thickness.
08What is Abrex 450 (NSSMC, Japan Make) used for?
Typical uses on this page include abrasion-exposed parts that also need good weldability and formability.
09Which certificate should I request?
An EN 10204 3.1 mill test certificate showing the brand and grade, heat number, chemistry and hardness, plus impact results where you specify a test temperature.
10How do I get a price and delivery date?
Send the brand and grade, thickness, size or cutting drawing, quantity, destination and required date through the enquiry form below, by WhatsApp or by phone.
