FAQ:

Q1: How soon can we receive the product after purchase?

A1: Within three days of placing an order, we will begin production. The specific shipping date is dependent upon international and government factors, but is typically 7 to 10 workdays.

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:What is the national standard of thread steel No. 8?
Rebar national standard: transverse rib nominal spacing shall not be greater than 0.7 times the nominal diameter of steel, the cross rib side and the steel surface of the angle of alpha may not be less than 45 degrees. When the steel nominal diameter less than 12mm, the relative rib area should not be less than 0.055, the nominal diameter of 14mm and 16mm, the relative rib area should not be less than 0.060, the nominal diameter is more than 16mm, the relative rib area should not be less than 0.065. Therefore, the nominal diameter of rebar No. 8 national standard steel bar relative rib area shall not be less than 0.055mm
Q:What is the content ratio of the screw steel and manganese steel?
The standard type of high manganese steel Mn13 steel and Hadfield steel, high manganese steel castings in China National Standard (GB/T5680-1998) grade: ZGMn13-1, ZGMn13-2, ZGMn13-3, ZGMn13-4, ZGMn13-5; ASTM (ASTMA128/A128M-1993) standard austenitic manganese steel casting steel are: ASTM-A (UNS-J9110.
Q:Are thread steels of coarse steel?
Thread steel does not belong to coarse steel, rough is shaped steel, fine is wire.
Q:14 screw steel 1 meters multiple?
Classified according to geometric shapes, according to the cross section of the rib section and the spacing of the ribs for classification or classification, such as the British Standard (BS4449), the thread steel is divided into type I, type ii. This classification mainly reflects the tightening performance of the threaded steel.
Q:How much is the minus difference per ton of thread steel?
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. The grade of thread steel is composed of the minimum value of the yield point of HRB and brand.
Q:What is the manufacturing process of the hot rolled thread steel production line?
Steel is produced by a small rolling mill, rolling mill main types are divided into: continuous and semi continuous and open train. New and used in the world, mostly continuous small rolling mill. Popular steel mills have universal high-speed rolling mills and 4 slitting high yield mills.
Q:How heavy can a 25 mm thread steel bear?
25 thread steel one meter 3.86kg.Method of calculation: 0.00617 times the square of the diameter of the steel bar. The weight of each diameter of the steel bar (kg) can be calculated.
Q:Does the grade three thread steel with "E" have the same information price as the ordinary three grade thread steel? Is there a big difference?
As far as I know, the price of information may not be divided into "E" and "E", but there are mandatory requirements on the standard. It is estimated that the price will not be much different.
Q:Thread steel 20*9 one is 2.001T. How many pieces of this one?
The weight of the thread steel = diameter * diameter *0.00617=20*20*0.00617=22KG, and then the total quality of this piece in the weight of a single thread steel, you can clearly get the number of roots.
Q:Is the steel thread stainless steel?
Steel is known as hot rolled ribbed bar. Ordinary hot rolled steel bars are made up of HRB and the minimum yield point of the 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 two levels, HRB335 (old No. 20MnSi), three HRB400 (20MnSiV, 20MnSiNb, old No. 20Mnti), four grade HRB500 three grade.
