PRODUCT CENTER
410 is a basic general-purpose martensitic stainless steel, used for high-stress parts, with good corrosion resistance and high strength and hardness. The alloy 410 contains at least 11.5 percent chromium, which is just enough to exhibit corrosion resistance in mild atmospheres, vapors, and many mild chemical environments.
420 is a hardenable martensitic stainless steel that contains at least 12% chromium, just enough to provide corrosion resistance. It has good ductility in the annealed condition, but can be hardened to a minimum Rockwell hardness of 50 HRC, which is the highest hardness in the 12% chromium scale.
Wire rod, also known as wire rod, usually refers to small diameter round steel in coils. The diameter of the wire rod is in the range of 5-19 mm (usually 6-9 mm), and its lower limit is the minimum size of the hot rolled steel section.

Wire rods are round steel with relatively small diameter. The commodity form is supplied in coils. On the construction site, the common ones are those with diameters of 6, 8, 10 and 12 mm, most of which are low carbon steel. Generally, they are not used for the main reinforcement of reinforced concrete structures, but are mainly used for making reinforcement sleeves. There are also small diameter "brick reinforcement" used in brick concrete structures.
H-beam is a kind of Economic section steel, which sectional area distribution is more optimized, the ratio of strength to weight is more reasonable, Mechanical properties of section is more better.It is developed from the I-section steel optimization of a better section mechanical properties of the economic section steel, because its section is same as the English letter "H" ,so be named as H-Beam. Because the various part of H-beam is arranged at right angles, H-beam has the advantages of strong bending resistance, simple construction, cost saving and light structural weight in all directions, so it has been widely used.

H-beam as a new type of economic construction steel. The section shape of H-beam steel is economical and reasonable, the mechanical properties are good, and the elongation of each point on the section is uniform and the internal stress is small. Compared with the ordinary I-beam steel, it has the advantages of more large section modulus,more light weight and more saving metal, which can reduce the building structure by 30-40%. And because its legs inside and outside parallel, leg end is a right Angle, assembled into components, can save the workload of welding and riveting up to 25%. It is often be used in large buildings (such as workshops, high-rise buildings, etc.), as well as Bridges, ships, lifting and transportation machinery, equipment foundation, supports, foundation piles, etc.
