a537 class 1 hardness Heat Treatment

Blast furnace ironmaking is a traditional ironmaking method based on coke energy. It cooperates with converter steelmaking and is the main method of producing a537 class 1 hardness steel at present. This dominance of blast furnace ironmaking is not expected to change for quite a long time. The essence of blast furnace ironmaking is the reduction of iron. Besides, coke is used as fuel and reducing agent. At high temperatures, iron ore or iron-containing raw materials are reduced from an oxide or mineral state to liquid pig iron.

a537 class 1 hardness, A335 P22 is a steel grade of American Standard boiler tube, and the executive standard is ASTM A335 / A335M, which is chromium molybdenum high temperature ferritic steel for boiler and superheater. A335P22 alloy pipe is mainly used as heating surface pipe of low and medium pressure boiler (working pressure is generally not more than 5.88 MPA, working temperature is below 450℃); A335P22 alloy pipe is also used as economizer, superheater, reheater and petrochemical industry pipe of high pressure boiler (working pressure is generally above 9.8MPa and working temperature is between 450℃ and 650℃).

As an experienced world class steel materials supplier and exporter, logistics and fast delivery is a crucial step to us. Our logistics department and shipping department take the responsiblity to allocate and transport steel materials from our mill and warehouse to customer port or designated destination. The cooperation of the two departemts are excellent and that powerfully support our fast delivery, and strive for shorter time for customers to receive steel materials.
