What is the difference between A573 gr 58 mill and A36 metals?

The company produces seamless steel pipes such as GB, ASTM, etc. all year round, including low and medium pressure boiler steel pipes, high pressure boiler steel pipes, A573 gr 58 mill seamless steel pipes for ships and petroleum cracking A573 gr 58 mill steel pipes, Seamless steel pipe, oil sleeve steel pipe, pipeline steel pipe, hollow sucker rod, common fluid steel pipe, structural pipe, kauden steel pipe, seawater corrosion-resistant titanium pipe and imported alloy steel pipe are used for high-pressure fertilizer equipment. The products are widely used in petroleum, chemical, electric, boiler, ship, machinery and other industries, and have been sold all over the country. Many A573 gr 58 mill products have been exported to the Middle East, India, Southeast Asia and Europe and America.

Low carbon alloy steel, the total amount of alloy elements is generally ≦3%; the low carbon alloy steel strength is significantly higher than that of carbon steel, with better plasticity and toughness, and weldability is acceptable; low alloy steel includes carbon manganese series, carbon manganese vanadium series, A573 gr 58 mill chromium molybdenum series, chromium molybdenum vanadium series. Molybdenum and chromium molybdenum vanadium alloy steels are commonly used as materials for hydrogen corrosion resistance, high temperature sulfur or hydrogen sulfide corrosion resistance and heat resistance (sub high temperature).

XAR450 steel is a special structural steel material with high wear resistance. The average hardness of this special wear-resistant structural steel is 450HB, which has high hardness and good toughness. The structure built with this steel is stronger, lighter and can withstand impact loads. XAR450 steel is used for wear parts-exposed structures such as protective pads, shell walls, support and reinforcement plates for excavators, mining machines and bulldozers.

The common delivery status of A573 gr 58 mill, SA516 Gr 70 plate is as follows:
1) SA516 Gr 70 plate quenching: the process of rapid cooling after heating to the temperature above the phase transformation point.
2) SA516 Gr 70 plate normalizing: after heating above the phase transition temperature, it is cooled normally (in air).
3) SA516 Gr 70 plate annealing: heating to above the phase transition temperature, cooling slowly.
4) SA516 Gr 70 plate tempering: after quenching, it is heated to a certain temperature (lower than the quenching temperature), kept warm, and then cooled.

A573 gr 58 mill, S235JR VS S275JR VS S355JR plates in yield strength: For plate thickness ≤16mm, the min. yield strength of S235JR plates is 235 Mpa, S275JR plates is 275 Mpa, S355JR plates is 355 Mpa. The yield strength of S235JR S275JR S355JR plates reduces with the increasing of plate thickness. S235JR VS S275JR VS S355JR plates in tensile strength: For plate thickness 3-100mm, the tensile strength of S235JR plates is 360-510 Mpa, S275JR plates is 410-560 Mpa, S355JR plates is 470-630 Mpa. For plate thickness 100-150mm, the tensile strength of S235JR plates is 350-500 Mpa, S275JR plates is 400-540 Mpa, S355JR plates is 450-600 Mpa.
