China A573 Gr.70 steel and S690QL steel plate prices continue to decline

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.70 steel and S690QL steel plate seamless steel pipes for ships and petroleum cracking A573 Gr.70 steel and S690QL steel plate 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.70 steel and S690QL steel plate products have been exported to the Middle East, India, Southeast Asia and Europe and America.

Marine steel plates are classified as medium-thick plates, hot-rolled steel plates used for manufacturing hull structures produced in accordance with the requirements of the classification society. First, the toughness of the marine steel ABS Grade A, A573 Gr.70 steel and S690QL steel plate, ABS EH36 plate is the most critical requirement. In addition, it requires higher strength, good corrosion resistance, welding performance, processing performance and surface quality.

Spring steel refers to the special alloy steel used to manufacture all kinds of springs and other elastic elements. A573 Gr.70 steel and S690QL steel plate, Spring steel has excellent comprehensive performance, good surface quality, accurate shape and size. Spring steel has hot rolled steel, cold drawn steel, cold rolled steel strip and so on. How much a ton of spring steel is related to the grade of spring steel, the market situation and the manufacturer.

A573 Gr.70 steel and S690QL steel plate, Wear-resistant steel plates are mainly made of some alloying elements, such as manganese, silicon, chromium, vanadium, aluminum, titanium, boron, rare earths elements and so on. Generally, manganese and silicon are added first, because this can further strengthen the deoxidation effect, and because their prices are relatively low, adding them early can ensure the yield of the elements added later.

A573 Gr.70 steel and S690QL steel plate, 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.
