Wear resistant steel plate AR360 AR400 AR500 NM360 NM400
NM360 belongs to wear-resistant steel plate (wear-resistant plate) series; Heat treatment: high temperature tempering, quenching + tempering (tempering) is widely used in mining machinery, coal mining machinery, environmental protection machinery, engineering machinery, etc., and is also commonly used as a yield strength ≥700MPa high-strength structural steel; Mainly in the need for wear-resistant occasions or parts to provide protection, so that the equipment life is longer, reduce maintenance caused by maintenance downtime, the corresponding reduction of capital investment; The yield strength is more than 800MPa and the tensile strength is more than 1000MPa.
Each batch of steel plate inspection items, sample quantity, sampling method and test method: shall comply with the provisions of the following table:
1 Stretch 1 GB/T2975 GB/T228
2 Impact 3 GB/T2975 GB/T229 GB
3 Bend 1 GB/T2975 GB/T232
4 Hardness 1 GB/T2975 GB/T231
Inspection rules:
1, steel plate inspection and acceptance by the supplier's quality supervision department.
2, steel sheet by sheet test mechanics. Among them, the supplementary inspection requirements shall be tested according to the same furnace number, the same thickness and the same delivery status.
3, Brinell hardness (HBW) test, according to the national standard GB/T231, the surface of the steel plate is milled off 1.0-2.5 mm, and then the hardness is tested on this surface
