FAQ:

Q1: Why buy Materials & Equipment from OKorder.com?

A1: All products offered byOKorder.com are carefully selected from China's most reliable manufacturing enterprises. Through its ISO certifications, OKorder.com adheres to the highest standards and a commitment to supply chain safety and customer satisfaction.

Q2: What makes stainless steel stainless?

A2: Stainless steel must contain at least 10.5 % chromium. It is this element that reacts with the oxygen in the air to form a complex chrome-oxide surface layer that is invisible but strong enough to prevent further oxygen from "staining" (rusting) the surface. Higher levels of chromium and the addition of other alloying elements such as nickel and molybdenum enhance this surface layer and improve the corrosion resistance of the stainless material.

Q3: Can stainless steel rust?

A3: Stainless does not "rust" as you think of regular steel rusting with a red oxide on the surface that flakes off. If you see red rust it is probably due to some iron particles that have contaminated the surface of the stainless steel and it is these iron particles that are rusting. Look at the source of the rusting and see if you can remove it from the surface.

Q:Is the theoretical weight of threaded steel and round steel the same?
The rebar is a kind of small section steel, mainly used for the skeleton of reinforced concrete construction members. In use, some mechanical strength, bending deformation property and welding performance are required. The raw steel billet for the production of threaded steel is carbon structural steel or low alloy structural steel which is treated by calm melting, and the finished steel bar is delivered in hot rolling forming, normalizing or hot rolling state.
Q:What specifications should be used for the three - step steel electroslag pressure welding electrode?
The electrode (coveredelectrode), is the metal coating in the welding core (coating), uniform centripetal pressure applied to core. The core metal cored electrode, in order to ensure the quality and performance of the weld, there are strict rules on the contents of metal elements in the core, especially for harmful impurities (such as sulfur, phosphorus content, etc.) should be strictly restricted, better than the base metal. The electrode consists of two cores and coating composition. The different cores are also different. The core components directly affect the composition and properties of the weld metal, so the harmful elements in the welding core to as little as possible.
Q:Now, the two project is to use rebar or rebar?
Of course, depends on what steel is used for components, such as the two structure of the structure column, and other minor parts, it does not matter.
Q:Two grade steel and three grade steel difference, the construction of the use of thread steel in general how to use the level?
The corresponding plasticity is a little worse. In the past, most of the rebar on the site was made of two grade steel. In the past few years, the country adjusted the standard brick, and gradually used three or even four steel. Two grade steel has been gradually withdrawn from the market, many large steel mills have not been produced
Q:What is the difference between rebar bolts and steel bars?
One is raw material and the other is finished product. Not to be confused. Shen bolt
Q:Is thread steel rod or wire?
10mm below can also be transferred to the wire, 10mm or more to the bar. Wire and rod are attributed to the bar, so there is no distinction between strictly.
Q:Why does the steel thread have longitudinal ribs?
Thread steel is inaccurate, commonly known as standard "deformed steel bars"". Hot rolled ribbed steel production in China, the surface usually with two longitudinal ribs and transverse ribs along the length direction of the uniform distribution, when the longitudinal section transverse rib crescent, and does not intersect with the longitudinal ribs, called crescent rib reinforced; when the longitudinal section is equal to the height, and with the intersection of longitudinal ribs, said for high ribbed bar. The second and third grade ribbed bars commonly used in engineering usually adopt the crescent rib surface shape.Similar to the screw thread, our country did not produce, it is said that there is such a shape abroad.If it is necessary to say that it is possible to strengthen the tensile and shear strength, because after all, the longitudinal rib expands a little of the cross section of the steel bar. But this is not the purpose of rolling longitudinal rib, the purpose of longitudinal rib is to improve the mechanical performance of the transverse rib.
Q:Why is the threaded steel thread?
The difference between round bar and round bar is that the surface has longitudinal ribs and transverse ribs, usually with two longitudinal ribs and transverse ribs uniformly distributed along the length direction. The rebar is a kind of small section steel, mainly used for the skeleton of reinforced concrete construction members. In use, some mechanical strength, bending deformation property and welding performance are required.
Q:What is the difference between the actual weight and the actual weight of the steel thread?
Is the difference between the work and the theory of weight. General steel factory, have weight difference, unlike canned beverage, not so accurate, this is called "bad" or "inferior". But the mills are not stupid, only under the poor, is not Quejinshaoliang, with a significant difference (such as standard 100KG, he will give you a 110KG).
Q:High strength thread steel hrb400e 32 in diameter, is it special steel?
In addition to high-quality carbon structural steel, carbon tool steel and carbon spring steel, the rest are alloy steel, and alloy steel accounts for about 70% of the special steel.
