Q 673 Steel strip type elastic ring hoop

Constant-tension spring-band Clamps for Firm Hose and Tube. These clamps have a wider band than other constant-tension clamps, which provides more coverage and reduces the chance of leaks.
The spring-action band lets the clamps automatically expand and contract with your hose or tube as temperatures fluctuate. Clamps are for firm plastic and rubber hoses and tubes.
Clamps with a black-phosphate finish provide mild corrosion resistance in dry environments.
Clamps with a zinc-plated finish resist corrosion in wet environments.
Note: When choosing a clamp, measure the outside diameter of your hose or tube with the fitting installed.    

In the development of fasteners, the production and development of the hoop, and clamp is more and more favored by the majority of manufacturers. How long to replace the gas hose band? Under normal circumstances, gas hoops should be used for two years to replace once. However, it should be noted that the summer weather is hot and humid, and the hoop has a certain impact on the public note the safety status of the hoop, found that the problem is the timely replacement, to ensure the safety of gas.Hardness: HRC:44-51, HY:435-530
Surface treatment: blackening
Material: manganese steel (65Mn, 1566)
Material properties: it is a wider use of carbon spring steel, compared with 65 steel, with high strength, hardness, elasticity, and hardenability, critical quenching diameter in the water is generally 30 ~ 50mm, and the oil is generally 16-32mm, heat treatment with superheat sensitivity and tempering brittleness tendency to water quenching easy to crack, the general use of oil quenching, the cross-sectional size of > 80 should be quenched and oil-cooled water quenching: annealing cutting is still good, but cold deformation plasticity is low, poor welding performance. However, the cold deformation plasticity is low, poor welding performance. This steel is generally used by pure fire, medium temperature tempering.
