.wp-image-1889{display:none;} In our today’s blog post about the fatigue strength of metals and alloys. Usually, this type of resistance is represented as S-N curves. Here the stress with the number of cycles to failure are related. High temperature fatigue. Temperature has a significant effect. It is well known that an increase in temperature always results […]

.wp-image-1278{display:none;} Screws are notched components. Why are they considered as such? For their threading. And where the screws are subjected to repeated and irregular stress? In some cases the break occurs in the first load-bearing part of the thread, at the entry into the internal (female) thread. (in 90%) What is it necessary for the

.wp-image-53{display:none;} Are metal sheets and  tapping screws contaminated? Are clients complaining about you? Here’s some useful tips to give them! What is the right material for the laminate and tapping screws? Tell your clients to be very careful with combination of materials to be used. These are some precaution to prevent the screws contamination: What

Application of Ring Screw:Ring screw should be mainly used in port, shipbuilding, railway, construction, plastic machinery, industrial control, pipeline auxiliary equipment, marine rescue, Airport construction, aerospace, venues and other important industries as well as infrastructure engineering machinery and equipment. Cautions for using application of ring screw: 1. Users must be trained before they can use

Generally, hanging ring bolts do not undergo surface treatment, but according to the requirements of use, they can be passivated by galvanizing, chromium plating and other surface treatment. Ring Bolts Surface Treatment Dehydrogenation should be carried out immediately after galvanizing. As a standard fastener, ring bolt is widely used in mechanical and electrical products. Its

At present, the standard Bolts Production Material on the market mainly include carbon steel, stainless steel and copper. Carbon steel: We distinguish low carbon steel, medium carbon steel and high carbon steel as well as alloy steel with carbon content in carbon steel. stainless steel: Performance rating: 45, 50, 60, 70, 80. copper: Common materials

There are two types of screw surface inspections, one is the inspection before the screw is produced, and the other is the inspection after the screw plating. Inspection method after screw treatment: Appearance quality requirements: The inspection of the appearance of the screws is carried out in terms of appearance, plating and other aspects. Inspection

Annealing: The wire is heated to a suitable temperature for a certain period of time, and then slowly cooled to adjust the crystal structure, reduce the hardness, and improve the normal temperature processability of the wire. Pickling: removes the oxide film on the surface of the wire and forms a phosphate film on the metal

Eyebolts Technical Requirements Eyebolts shall be made of 20 or 25 steel (GB699). The eyebolts must be integrally forged. Forgings should be normalized and the scale removed. The grain size of the finished product should not be lower than Grade 5 (GB6394), and the forgings should not have over-burning or crack defects. In order to
