Usage and Applications of Hot Rolled Round Bar

1. Hot rolled round bar of 6-25mm, or small round is mostly used for straight bundles supply, and used for steel, bolts and various mechanical parts. While the bigger round bar, or more than 25mm hot rolled bar, is mainly for the manufacture of mechanical parts or for seamless steel billet.

2. 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.

* If you would like to get our price, please inform us the size, standard/material and quantity. Thank you very much for your attention.

Q:Three - grade thread Phi 10 steel can replace a grade Phi 12 round bar? Which elder knows, trouble pointing.
The general situation is not possible, but sometimes as stirrup time, and has little effect on the structure, if 12 reinforced with missing a few, but not on the main force position is possible, sometimes supervision is not allowed.
Q:Use of stainless steel round bar?
Stainless steel round bar has a broad application prospect, and is widely used in hardware, kitchenware, shipbuilding, petrochemical, machinery, medicine, food, electricity, energy, aerospace and other architectural decoration. Equipment, chemicals, dyes, paper making, oxalic acid, fertilizer, etc.; equipment for photography, food industry, coastal areas, ropes, CD poles, bolts, nuts, etc..
Q:What is the tensile strength of Q235 round steel?
Level 1, surface shape, light circle, strength code R235, grade Q235, carbon content 0.14%-0.22%. Silicon content 0.12%-0.30%. Manganese content 0.30%-0.65%, phosphorus content is equal to less than 0.045%, sulfur content is less than or equal to 0.050%,
Q:Cold drawn steel wire is a round bar or thread steel in Construction Engineering?
Cold drawn steel wire should be the same as round steel and thread steel! Their forming process and the meaning of the place used are different, and the quota is also different, cold drawn steel wire is cold drawn steel wire, strictly speaking, there is no mix together.
Q:What's the difference between Q345 round steel and No. 45 round steel material?
Q345 round steel is different from round steel No. 45:Q345 round steel containing Mn, but containing C below 45# round bar45# round steel containing C is higher than Q345 round steel, but without Mn
Q:How many positive and negative tolerances are allowed for round steel GB?
Round steel is a solid strip of steel whose cross section is round. The specifications are expressed in millimeters of diameter, such as "50", which means a round bar of 50 millimeters in diameter. Round bar is divided into three parts: hot rolling, forging and cold drawing. Standard Specification for hot rolled round steel is 5.5-250 mm. Among them, 5.5-25 mm small round bars are mostly supplied by straight strips. They are used as reinforcing bars, bolts and various mechanical parts. They are more than 25 millimeters of round steel. They are mainly used in the manufacture of mechanical parts or seamless steel tube billets
Q:What's the difference between bearing steel and round steel?
Steel: steel widely used, a wide range of products, according to the shape of the cross section, the steel is generally divided into profiles, plates, pipes and metal products in four categories. Steel is a material of shape, size, and performance made by pressure processing of ingots, billets, or steel. Most steel processing is through the pressure processing, so that the processed steel (billets, ingots, etc.) plastic deformation. According to the steel processing temperature, can be divided into cold processing and hot processing two.
Q:How to determine the welding seam height of steel plate and steel bar?
How to determine the welding seam height of steel plate and steel bar?:If the steel plate surface and steel end vertical welding, welding angle height depends on the diameter of the steel, general welding angle height is 0.7 times the diameter of reinforcement;
Q:Do you need paint for roof lightning proof steel bars?
The roof of the round steel as long as the welded joints painted anti rust paint is good, should not be painted a large area. When the flash device is made of steel material, hot-dip galvanized steel shall be used and corrosion resistant by zinc plating.
Q:What is the reason that the diameter 130-45 round steel will break after welding?
Steel No. 45 belongs to medium carbon steel. Because of its high carbon content, it has poor weldability, but its comprehensive property is good. If welding is needed, it needs to be preheated before welding and heat treated after welding to reduce its internal stress. The more commonly used weldability is No. 20 steel. In order to improve the performance of No. 20 steel, heat treatment is usually applied to its surface.
