Technical data of the original chemical composition (%)
- Q:How many kinds of steel are needed to build the building?
- According to the processing methods can be divided into: hot rolled steel, heat treatment, cold drawn steel, steel cold drawn low carbon steel wire and steel wire tube; surface shape can be divided into smooth steel and thread; according to the varieties of steel can be divided into low carbon steel, medium carbon steel, high carbon steel and alloy steel etc.. The strength of China's steel bars can be divided into five grades: I, II, III, IV and V.
- Q:JL32 is the finish thread heavy bar 32? What's the difference between normal and ordinary? What does the front JL32 mean?
- Finishing rolling rebar diameter of JL32-- 32mm, 32 - screw steel hot rolled ribbed steel bars, the difference between the two: 1, ribbed bar is injected directly into the concrete, increase of steel concrete.
- Q:What is the difference between drawing steel and round steel on drawing?
- When drawing steel, it should be used to correct the name: ribbed steel bar, whose name is abbreviated as "HRB" in English. At the same time, according to the characteristic value of yield strength, it can be divided into three grades: HRB335, HRB400 and HRB500, and should be marked when marked.Bar diameter and material should be marked on the drawing, such as material of 35 / Cr12.
- Q:How to recognize high quality thread steel
- Inferior steel due to poor production conditions, bulk, no metal signs, no quality guarantee. For safety reasons, we should not buy the inferior steel bars, or go to the direct agents of some famous brand manufacturers, so that the quality is guaranteed. Shandong hundred fertile Steel Pipe Co., Ltd. here recommends that users in the purchase of thread steel, must go to the formal steel business units to purchase, request steel quality certificate, and acceptance.
- Q:Why can not the finish thread steel be welded?
- This is generally superior to alloy steel. Carbon content is relatively high, poor weldability, welding conditions are very demanding, but also produce high temperature welding, it is easy to destroy the original material performance. So, under normal circumstances, on-site welding is not allowed.
- Q:What is the difference between the material of steel thread and its use?
- The grade of thread steel is composed of the minimum value of the yield point of HRB and brand. H, R, and B are the first letters in English for hot-rolled (Hotrolled), ribbed (Ribbed) and reinforced (Bars) three words. Hot rolled ribbed bar is divided into HRB335 (old No. 20MnSi), HRB400 (20MnSiV, 20MnSiNb, veteran, 20Mnti), HRB500 three brands.
- Q:How much is the minus difference per ton of thread steel?
- H, R, and B are the first letters in English for hot-rolled (Hotrolled), ribbed (Ribbed) and reinforced (Bars) three words. Hot rolled ribbed bar is divided into HRB335 (old No. 20MnSi), HRB400 (20MnSiV, 20MnSiNb, veteran, 20Mnti), HRB500 three brands.
- Q:Cast-in-place with 10 mm reinforcement, a good layer or 8 mm double layer? Why?
- If the reinforcement ratio of the situation, the use of 8 mm double reinforced than a layer of 10 mm steel is better, while using the double reinforced cast-in-place floor to prevent from the temperature shrinkage stress is good Oh, can actually try to use reinforced reinforcement ratio is moderate Oh, the only way to ensure the floor the panel does not appear the phenomenon of cracking, especially the roof panel, reinforcement ratio is very important.
- Q:How much is the weight of 6mm thread steel KG?
- The two grade steel is 847kg, the three grade steel is 1017kg, and the four grade steel is 1229kg
- Q:Is the steel thread stainless steel?
- Threaded steel is construction steel, not stainless steel.
