What is cabinet hinge made of? It is the common question that clients asked Kingwen Liang.
Hinge, in the spring kav hinge which Kingwen Liang engaged in, most of them use the cold-rolled steel Q195. About the knowledge of cold-rolled steel, please pay attention to the article below:
The use and classification of cold-rolled steel and cold-rolled coil
Cold-rolled steel, the cold-rolled thin steel is short for the ordinary carbon structure cold-rolled steel, is known as the cold steel, sometimes it will be mistakenly written as cold plate. The cold plate is composed of ordinary carbon structural steel hot-steel,
After further cold-rolled it will become the steel that the thickness is less than 4mm. Since the rolling is at a room temperature, it does not produce iron oxide, so it has high surface quality and high toughness, plus the annealing treatment, the mechanical properties and process performance is better than hot-rolled steel. In many fields, especially in the electrical appliance area, has gradually replaced the hot-rolled steel.
Applicable grades: Q195 Q215 Q235 Q275 SPCC (Japan brand) ST12 (Germany brand)

Symbol:
- Q- The code of common carbon structure steel point (limit), it is the first Chinese alphabet, 195 215 235 255 275- respectively the number of their yield point, unit: MPa (N/mm2). Since Q235 steel is better in the strength, plasticity, toughness and weld ability, can meet the general use demands better, so it is widely used in the area.
- S- For steel, P-For plate, C-For cold and the fourth C-For common
- ST-For steel, 12-for ordinary thin sold-rolled steel
Cold-rolled steel: Steel No. - Technology standard
Samples: B-0.57501500-GB708-88, steel standard No.is Q/BQB402, the grade is SPCC, heat annealing treatment plus formation (S), the central processing state is linen D, surface quality is the FB level trimming (cutting edge is EC, not trimming is EM) steel, thickness is 0.5mm, B-level, width is 1000mm, A-level, length is 2000mm, A-level, roughness accuracy PF, so is marked as :Steel ECQ/BQB 402-SPCC-SD-FB/(0.51000A2000A-PF.A)
Cold-rolled steel: Q225-GB912-89
Main origin: Bao Steel An Steel Ben Steel Wu Steel Han Steel Bao Steel Tang Steel Lian Steel Ji Steel and so on.
Ordinary cold-rolled steel: is made up of the ordinary carbon structure. Cabinet hingehas a perfect surface quality, with good punching properties, it requires the cold-rolled and cup test pass, was usually used in the automotive and other industries and coated sheet materials.
High-quality cold-rolled steel: mainly include all kinds of high quality cold-rolled steel; the most commonly used is carbon structural steel, especially deep drawing cold-rolled steel, is made of high quality carbon steel 08A1, the steel surface quality can be divided into three groups: I II III, respectively especially senior, senior and junior surface finishing. By drawing level is divided into ZF HF F grade(stand for Punch drawing the most complex, very complex and the complex parts) , according to the thickness tolerance, is divided into A and B two precision, widely used in automobile and tractor industries
Cold-rolled steel, with smooth surface, fine processing, it is widely used in cars, refrigerators, washing machines and other appliances, industrial equipment and various construction materials. With the development of economics, cold-rolled steel has been called the certain material in the modern society. Classification of cold-rolled products: hot rolled pickling, rolling hard, ordinary cold-rolled, galvanized (galvanized fingerprint resistant, hot dip galvanized), zinc, tin plating, coating, electrical steel (silicon steel) and so on.
Kav hinge is your best choice.
