Product Description:

Product Description:

Hot Rolled Round Steel Bars with Cr A36, Q235, SS400 is used for manufacturing ball, roller bearing steel and rings. Bearing in work is under great pressure and friction, so have high demands bearing steel and hardness and resistance, and high elastic limit.

Bearing steels are used for ball and roller bearing applications and are comprised of low carbon steels and high carbon through harden able steel.

For example, bearing ring, steel rolling mill, machinery, 100Cr6 bearing steel ball is widely used in high-speed and low-noise bearing, bicycle, motorcycle, automobile, bags electronically.

 

Product Applications:

Hot Rolled Round Steel Bars with Cr A36, Q235, SS400 are ideal for structural applications and are widely used in the construction of buildings and bridges, and the manufacturing, petrochemical, and transportation industries.

1. Steel round bar products is used in construction and a large number of architectural and engineering structures. And it can be used in production of handrail, windows, machinery, telecom and curtain wall.

2. It can be used in the fields like metal mines, cement plants, water coal slurry, power stations and chemical industry.

3. Besides, we can supply some especial material steel round bar that can be used for main shaft of steamer, hummer shank, with big section and supper force.

4. Recommended watchcase factory, screw factory and other cold stamping products industry use.

 

Product Advantages:

OKorder's Hot Rolled Round Steel Bars with Cr A36, Q235, SS400 are durable, strong, and resist corrosion.

1. The steel in which the main interstitial alloying constituent is carbon in the range of 0.12–2.0%.

2. As the carbon percentage content rises, steel has the ability to become harder and stronger through heat treating; however it becomes less ductile.

3. Regardless of the heat treatment, higher carbon content reduces weld ability. In carbon steels, the higher carbon content lowers the melting point.

4. Quality should be in conformity with the specification of the manufacturer. Quantity and packing conditions should be in conformity with the term in the contract.

 

Main Product Features:

·         Premium quality

·         Prompt delivery & seaworthy packing (30 days after receiving deposit)

·         Corrosion resistance

·         Can be recycled and reused

·         Mill test certification

·         Professional Service

Q:How much is the thick wall hollow square 30*30
Square: solid, bar. Different from the square pipe, hollow, belong to the pipe. Steel (Steel): material of various shapes, sizes, and properties required by pressure processing for ingots, billets, or steels.
Q:Twist steel (twisting steel) there is no standard?
Lattice steel plate steel bar is also called twist, the steel twisted shape, so only when the square size annotation annotation, common general specifications for 8*8mm, 6*6mm, 5*5mm, in the standard steel plate, the bar is defined as fixed on the bearing flat steel, round steel, square steel twisted or flat, that is say, don't necessarily use twisted steel (steel twist) but hot dip galvanized steel grid plate used in the steel industry used torsion, stainless steel using round steel, and make use of flat bar made of steel plate. We called steel grid plate or pressure locking steel plate, steel plate of GB also do this cross sectional area:: twisted steel, round steel bar with flat steel, its cross-sectional area of not less than 20 mm.
Q:Building with steel or steel plate?
Recommended use of channel ten, three meters span is not large, there will be no vibration problems! Do not use the bearing structure of square steel tube, the solid steel with the specifications of the cost is too high and the bending strength is hollow, not recommended.
Q:How to make the steel arc
If reinforced by 1. fold 2. arc bending machine flame cutting machine 4. fold 3. baking arc building arc roll can be solid steel grip bending machine processing.
Q:Building height is 5m, the main dry hanging stone square spacing value should be how much better?
Say so much, directly tell you, if it is with square steel (main keel), that spacing in 1--1.2 meters is absolutely no problem, the standard is not allowed more than 1.2 meters, but the actual construction exceeds the situation or some. If there is no special circumstances (such as from the wall out more than 300mm or), then no problem, rest assured!!!
Q:How to connect with steel purlin roof
The steel wall frame generally refers to the glass curtain wall of the airport, or the windbreak wall of the coal yard. It is the wall structure, and the former two are the roof structure.
Q:The difference between cold and hot galvanized steel hollow where
Hot rolling process is: the ingot directly into square tube, and then galvanized, also known as seamless pipe.Usually than cold-rolled steel hot-rolled square steel prices high.
Q:The difference between staircase truss square steel tube and angle steel
Square steel tube, large diameter thick walled square steel tube, square steel tube, seamless square steel low alloy square steel tube, 135*135*10 square steel tower with square steel tube, Q345B low alloy square steel pipe, seamless steel pipe 20# square
Q:You need to light steel keel wall square steel
Needed. The material of the light steel keel partition wall is galvanized iron plate, the pressed keel and the gypsum board (or calcium silicate board), its merit is the light weight, easy to walk the electric wire tube, the construction is quick. But the fire is not good, it is dry work. The cost is higher.
Q:How can we see is galvanized steel or wood
The first dip galvanized pipe is a hot-rolled or cold-rolled galvanized steel or galvanized sheet for the blank shape by the cold bending process after section steel pipe welded square hollow square cross-section shape and size of the high-frequency. Or the cold formed hollow steel pipe prepared in advance will be galvanized by hot-dip galvanizing.
