Introduction

Ordinary carbon structural steel and ordinary carbon steel. The carboncontent of less than 0.25% 0.06-0.22%, the most commonly used. Belongs to the low carbon steel, in each metal steel grades, minimum yield point thickness is less than 16mm. Compared with high-quality carbon structural steel, carbon content, performance and phosphorus, sulfur and other residual element content range. Provide security conditions in the China and some countries,ordinary carbon steel is divided into three categories: Steel (Xing Gang), only to ensure that the mechanical properties, does not guarantee the chemical composition, type B steel (B steel), only to ensure that the chemical composition, does not guarantee the special mechanical properties; steel(steel). Not only guarantee the chemical composition and mechanical properties, guarantee. Manufacturing structural components often used in special steel is very important..

Component is mainly used for the production of carbon structure steel structure engineering. It is commonly used to supply conditions, high sulfur,phosphorus content in steel, allows up to 0.050% and 0.045% respectively.Steel accounted for a larger proportion, total output in this steel.

3 application of this kind of steel from oxygen converter, open hearth furnaceor electric furnacesmelting, hot rolled steel, steel strip, the general part and bar. Plate usually volume (including control rolling) or normalizing treatment delivery. The chemical composition of the steel, mechanical properties, andbendingperformance shall comply with the relevant provisions.

In the Chinese national standard GB700-88 steel according to yield values are divided into 5 grades, and by mass is divided into 4 level. With the letter Qsymbol level, yield, yield value, quality rating symbol, consisting of 4 parts of the deoxidation method according to the order of.

The scope of application of this kind of steel is very extensive, mainly used for welding, riveting or steel structural bolts, minority is producing all kinds of machinery parts. Q195, and low strength of Q215 steel, the production of low carbon steel wire. Stainless steel wire mesh, the roof plate, welded steel pipe,anchor bolts and rivets etc.. Q235 steel of moderate intensity, and has good plasticity and toughness, easy forming and welding. This steel usually used for reinforcing steel structure, also used as a rivet, a railroad spike and variousmechanical parts, such as bolts, connecting rod, connecting rod. 255, Q275 high strength steel used in agricultural machinery production, can also be used as reinforcement of railway fishplate.

According to the special requirements for steel performance in some industries, for ordinary carbon structural steel composition adjustment and a series of professional steel after forming, such as cold heading steel, bridge steel, pressure vessel steel, steel, steel for boiler. In addition to the chemical composition of the strict control of steel used, so that the performance of the conventional, but also provides some special inspection of the project, such as low temperature impact toughness, aging sensitivity, gas in steel, inclusions and fracture etc..

Overview of Q235A features and scope of applications: Q235A toughness and the plasticity is good, have certain elongation, has good welding properties and hot workability. Q235A is generally used in hot rolling state, with steel, the rolling steel, steel plate, steel pipe can be used for welded structures, bridges and generally not important machine parts manufacturing all kinds of, such as bolts, rivets, rings and connecting rod, etc..

Said method: the symbolic quality rating symbol + deoxidation method of Q+ digital + composition. Its steel dubbed "Q", representing the yield point of steel, behind the figures to show that the yield point value units are MPa Q235 says such yield point (s) of carbon structural steel, 235 MPa. The necessary grades can be followed Mark said quality grade and deoxidizing method symbol. Quality level symbols are for A, B, C, D. Deoxidation method symbol: F said rimming steel;

B said semi killed steel: Z said calm steel; TZ said special calm steel, steel standard symbols not calm, namely Z and TZ are not standard. For example, Q235-AF said a rimmed steel. Carbon steel specially uses, such as for bridge steel.

Q:What is the function of an automobile leaf spring?
Spring: the multi length and unequal curvature of the folded plate. After installation ends naturally curved upward. When the impact force of the wheel face came when the steel plate deformation, play a buffer, damping effect
Q:What is steel concrete?
Steel plate concrete is generally called SRC, that is, the steel part is changed into steel plate, basically the concrete is poured on the steel plate. Specific reference, construction manual fourth edition.
Q:How can steel plates with a thickness of 1MM be welded?
1mm steel plate is best made by spot welding or flash welding, for example, electrical welding will cause plate deformation
Q:Stainless steel plate how to cast mirror plate?
Jacksonlea brand stainless steel polishing pasteThe supply of Jacksonlea brand stainless steel polishing paste, with the use of polishing wheel, can provide excellent gloss, providing the whole face of Gaoping. According to the customer's quality requirements, can provide rough, medium, fine specifications, with cloth, hemp wheel use.
Q:What is the difference between Q235A steel and Q235B steel?
Generally, the steel plate is made on the surface of the steel plate before the finished steel plate leaves the factory. If the profiles, such as: angle steel, channel steel, I-beam, H steel and other steel products, steel products in the finished section before leaving the factory on the signs marked. The user can identify whether the material is Q235A, or Q235B, or other material.
Q:Which is good, z15 grade steel plate and z25 grade steel plate?
It is obvious that the fracture resistance of lamellar fracture is stronger than that of fracture shrinkage, that is, the lamellar tearing resistance of Z25 is better than that of Z15.
Q:What is the electromagnetic steel plate in the generator?
Looks like in the game but did not listen to the words, said in real life. Not heard of steel sheet of motor core
Q:Are there any restrictions on the thickness of the steel plate, such as the minimum thickness of the steel plate?
If the intensity is enough, you should be the first 4mm for the economy. Carbon steel plate, with electrode arc welding, 2 diameter welding electrode on line.If it is stainless steel, tungsten argon arc welding is better
Q:What are the rental costs for steel sheet piles?
According to the different processing technology, it can be divided into hot rolled / stretched steel sheet pile and cold rolled steel sheet pile. Now, due to the production conditions and scale constraints, hot rolled steel sheet pile has no production line in China, and the rolled steel sheet piles used in China are all from abroad.
Q:Is galvanized steel plate or iron plate?
From the point of view of metal science, there is a misunderstanding here. If you want to be familiar with the metal science, you will not ask this question. This is also a misunderstanding that many people coexist.
