In terms of technology, we often say "High strength steel" generally means that the yield strength four hundred and sixty Steel above MPa. This kind of steel has high strength, good ductility and stability, and has high comprehensive mechanical properties, especially in the normalized or normalized plus tempered state.

In this issue, the editor mainly introduces the high strength steel series products of Haoxuan International:

1、 Product No.: HG60

HG60 It is a kind of high-strength structural steel with high strength and good fatigue resistance, high toughness and low brittle transition temperature, good cold forming performance and welding performance, good corrosion resistance and certain wear resistance. G60 express sixty kg . Level, product parameter It can be widely used in engineering machinery, automobile processing, general machinery, coal machinery and other fields.

2、 Product No.: HG70

HG seven zero It is a kind of high-strength structural steel, Overall performance and HG60 The products are very similar, with high strength, high toughness, good cold forming and welding performance, good corrosion resistance and certain wear resistance, G70 It indicates that such products are seventy Kg. It is generally applicable to engineering machinery, automobile processing, general machinery, coal machinery and other fields.

3、 Product No.: HG785

HG785 High strength welded structural steel ， seven hundred and eighty-five The tensile strength of the steel plate is about 785Mpa The steel has high yield strength and tensile strength, and can be used as large steel structural parts of coal mining machinery, mining machinery, etc. Its practical application covers many industries.

4、 Product No.: Q460D

Q460 On the basis of ensuring low carbon equivalent, the content of micro alloy elements is appropriately increased . As a low-alloy high-strength steel, elongation ≥ 17% 。 Good welding performance requires low carbon equivalent of steel, and the increase of microalloying elements will increase the carbon equivalent of steel while increasing the strength of steel. Fortunately, the increased carbon equivalent is very small, so it will not affect the weldability of steel.

5、 Product No.: Q550D

Yield is five hundred and fifty High strength at MPa D The overall application scope of Grade I steel is relatively moderate. It is generally smelted by converter or electric furnace, and refined outside the furnace when necessary. The delivery status is usually in the quenched and tempered state. It is mainly used in important (low temperature) high-strength structural parts, engineering machinery, mining steel structural parts, etc.

6、 Product No.: Q690D

The yield strength is six hundred and ninety High strength at MPa D Grade I steel, low temperature resistance, high tensile strength, usually delivered in quenched and tempered state. It can be widely used in coal mining machinery, engineering machinery, hydraulic support, port cranes, flat transporters and other large machinery structures.

7、 Product No.: Q960E

Q960 E It belongs to quenched and tempered high strength steel plate , yield strength nine hundred and sixty Megapascal, grade E level ， This kind of steel has high yield strength, high tensile strength and other characteristics, and is mainly used in large construction machinery manufacturing and other fields.

8、 Product No.: Q1100E

Q1100E The steel plate belongs to high-strength steel plate, which is quenched by the manager + It is all martensite high-strength structural steel plate with adjustment treatment. The delivery state is quenching and tempering, with excellent welding performance and cold forming processing performance. It is mainly used in construction machinery boom, lifting equipment structure, truck crane and truck mounted boom, transportation equipment, special containers, drilling platforms and other fields, as well as other various outriggers.
