N/A This steels is used in the manufacture and maintenance of plows and various other agricultural implements, such as sub-soilers, ditchers, border ridgers, cultivators, furrowers, and harrows. It is also used in the manufacture and maintenance of construction machinery, such as tractors, scrapers, bulldozers, shovels, concrete mixers, etc. Other applications include brake dies, brake bands, racks, slides, etc.

N/A The following values are typical for 1" thickness and may be considered as representative in the as-rolled condition:
Tensile Strength - 90.000 psi
Yield Point - 55,000 psi
Elongation in 2" - 23%
Reduction of Area - 45%
Brinell Hardness - 201

N/A This material is generally machined in the as-rolled condition without difficulty. Average cutting speed is 85 surface feet per minute.

N/A May be welded with proper precautions. With thin sections and a flexible design, gas or arc welding may be used without preheating; but in joints over 1/2" to 3/4" thick preheating is necessary. To develop equivalent strength in a weld, a low-alloy filler is recommended. Stress relieving is also recommended. The grade of welding rod to be used depends on thickness of section, design, service requirements, etc.

N/A Heat to 2100°-2200°F.

N/A Heat to 1550°-1650°F. Cool in air.

N/A Heat to 1450°-1550°F. Cool in furnace.Average Brinell hardness 192.

N/A The recommended quenching temperature is 1450°-1550°F for oil, or 25° lower for water. Temper to required hardness.
