ASTM A 709 Gr.50W weathering steel plate has good impact resistance

1. ASTM A 709 Gr.50W weathering steel plate has good impact resistance.

The base material of ASTM A 709 Gr.50W weathering steel plate is low carbon steel or low alloy. A tough material like stainless steel embodies the superiority of bimetal. The wear-resistant layer is resistant to media and abrasion, and the base material bears the media and load, so ASTM A 709 Gr.50W weathering steel plate has good impact resistance. It can withstand the impact and wear of the high drop hopper in the material conveying system.

2. ASTM A 709 Gr.50W weathering steel plate has good heat resistance
The alloy wear-resistant layer is recommended to be used at 600 hours. The alloy wear-resistant layer is added with alloys such as vanadium and molybdenum, which can withstand high temperature wear of 800.

The recommended temperature is as follows: It is recommended to use ordinary carbon steel substrate at a temperature not higher than 380. Low-alloy heat-resistant steel plates (15CrMo, 12Cr1MOV, etc.).

It is recommended to use it at a temperature not higher than 540. The heat-resistant stainless steel substrate is recommended to be used at a temperature not higher than 800.

3. ASTM A 709 Gr.50W weathering steel plate has good corrosion resistance
The alloy layer of ASTM A 709 Gr.50W weathering steel plate contains a high percentage of metallic chromium, so it has certain rust and corrosion resistance. It can be used in coal troughs and hoppers to prevent coal sticking.
