- Q:What's the best way to open a 10mm thick steel sheet?
- Steel plate is a kind of flat steel with big width ratio and large surface area. According to the thickness of plate Ya divided into thick and thin plates two specifications.
- Q:How can the white steel plate be bright and cleaned?
- The use of detergent plus iron cloth rub, salt, vinegar 50 ml into the bowl, then add a little detergent thoroughly, with a cloth dipped in salt and vinegar detergent water rubbed white plate, not only can remove stains, can maintain the original brightness.
- Q:Why can steel HPB300, steel plate without Q300, steel structure manuscript review, but also continued the Q235, why not improve it?
- Carbon steel according to the steel yield strength is divided into 5 grades: Q195, Q215, Q235, Q255 and Q275 of each grade because the quality is divided into A, B, C, D grade, with a maximum of four kinds, some only one; this is just plain carbon steel, the price is cheap, generally not heat treatment. Only quality carbon steel has the value of heat treatment.
- Q:The differences and uses of cold rolling and hot rolling
- Cold rolled forming steel allows partial buckling of the cross section, thus taking full advantage of the post buckling capacity of the member, while the hot-rolled section does not allow partial buckling of the cross section.
- Q:What kind of material does ordinary steel plate refer to in steel market?
- Wear resistance and special electromagnetic properties, carbon steel in this respect is relatively poor, because in the manufacture of this kind of steel plate, often to maintain good toughness, so we reduced the iron element to join. Not as a result of the steel sheet in abrasion resistance and special electromagnetic aspects is very weak, but the alloy plate is different because adding other alloying elements, which makes the original in iron deficiency situation has been greatly improved this is better for some special requirements of customers.
- Q:How much is 2 millimeters per square meter?
- The performance of carbon steel mainly has the following deficiencies:(1) hardenability is low. Under normal circumstances, the maximum quenching diameter of carbon steel water quenching is only 10mm-20mm.(2) strength and yield strength are relatively low, such as the s of ordinary carbon steel Q235 is 235MPa, while that of low alloy structural steel 16Mn is 360MPa and above s. The sigma S / sigma B of steel 40 is only 0.43, much lower than that of alloy steel.(3) the stability of tempering tempering stability, carbon steel in quenching and tempering treatment, in order to ensure the high strength with the tempering temperature is lower, so the toughness of the steel is lower; in order to ensure good toughness, with high tempering temperature strength is low, the mechanical properties of carbon steel level is not high.(4) stainless steel can not meet the requirements of special performance. Carbon steel is often poor in oxidation resistance, corrosion resistance, heat resistance, low temperature resistance, wear resistance and special electromagnetic properties, and can not meet the needs of special performance.
- Q:What is the difference between an open plate and an original plate?
- Open and flat from the original flat surface color to distinguish. Because the Kaiping plate originally is rolled strip, the oxide is less, the same time the Kaiping plate and the original flat for a period of time after the original flat in different colors, red, and blue plates.
- Q:What's the difference between hot-rolled seamless steel tube and cold-rolled seamless steel tube?
- Cold rolled seamless steel pipe (DIAL) in general, steel pipe for low and medium pressure boiler tube, high-pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, oil cracking tube and other steel tube, including carbon thin-walled steel, alloy thin-walled steel, stainless steel, thin steel tube.
- Q:What is a fixed length steel plate?
- Fixed length: it is a kind of commonly used steel specification, which means that the size of steel supplied is certain.
- Q:How much is a steel sheet per square meter?
- Steel plates are priced by weight. They are different from one square meter in thickness and weight. The price is different.
