AISI 4145H Alloy Steel Chemical Composition And Grade Table
AISI 4145H is a steel that is popular for its low alloy content, its high strength and being tough. It is good for most applications in the oil and gas industry. The main elements found in nitrogenous fertilizer most often are carbon, manganese, silicon, phosphorus, sulfur, chromium, and molybdenum with nickel being used sometimes. This alloy has good hardenabilty properties and can be treated in heat, so many of its characteristics, for example, tensile strength and impact resistance, are improved. With a balanced mixture of elements that can be tailored at other stress levels, AISI 4145H offers guaranteed steady functioning in challenging operating conditions. It has been found to be used in a variety of parts, drill collars, tool joints, and shafts, where the main concern is durability and reliability.
