8740 Alloy Steel Bar Stock

8740 Alloy bar stock is a nickel-chromium-molybdenum low-alloy steel that has incredibly good hardenability, strength, and toughness properties.

8740 ALLOY STEEL BAR STOCK THAT HAS INCREDIBLY GOOD TOUGHNESS PROPERTIES

8740 Alloy bar stock is a nickel-chromium-molybdenum low-alloy steel that has incredibly good hardenability, strength, and toughness properties. 

8740 alloy round bar stock finds its uses in a number of applications where strength, toughness, and wear resistance are taken into high consideration as it plays vital importance when forging this kind of metal. This alloy is particularly used as high-forged fasteners. 

The chemical composition of 8740 alloy bar stock consists of Carbon 0.38 – 0.43. Manganese 0.75 – 1.00, Phosphorus 0.035 max, Sulfur 0.040 max, Silicon 0.20 – 0.35, Nickel 0.40 – 0.070, Chromium 0.80 – 1.10, and Molybdenum 0.15 – 0.25. Based on its chemical analysis alone it is fair to see why this metal is forged at a starting temperature of around 2200F (1205C) and can be forged down to approximately 1700F (925C).

ALLOY 8740 STEEL APPLICATIONS

With excellent toughness, high fatigue strength, and outstanding machinability,8740 steel has indeed become a staple for most industries in the Midwest.

8740 alloy steel is a high-strength, low-alloy steel that is used in various applications such as gas turbines, gas compressors, and high-pressure boilers. 8740 steel is one of the most popular alloy steels for heavy structural applications because it offers good strength and toughness at elevated temperatures, weldability, and excellent corrosion resistance to many corrosive environments such as seawater or sewage sludge.

8740 steel is also known for its high corrosion resistance properties, making it a good choice for marine environments and other highly corrosive conditions. The 8740 steel is a type of alloy containing nickel, chromium, and molybdenum. It is also one of the world’s most widely used types of steel. It can be used for a wide range of applications such as: pressure vessels, boilers, storage tanks, heat exchangers, and piping.

8740 alloy steel is high-strength, low-alloy steel. It has excellent toughness and weldability, and is used in producing gears, sprockets, chains, shafts, and other products. 8740 alloy steel is high-strength, low-alloy steel. Also, it is a high-strength, high-hardness, low-alloy steel. It is a common grade of steel used in the production of springs. It has excellent mechanical properties and good corrosion resistance.

The alloy content of this type of metal is typically 0.25% to 1%. In the steel industry, 8740 steel is a type of alloy composed of nickel, chromium, and molybdenum. It is a tough alloy that can be applied in high-strength applications. It has a carbon content of 0.35% to 0.45%, making it resistant to corrosion and pitting.
