Stainless Steel: Stainless Steel is excellent at resisting corrosion either from fluids or the external environment. An alloy of steel that contains more than 10.5% chromium, with a temperature range of –254°C to 649°C and with fittings often rated to 10,000 psi (up to 20,000 if specially designed) stainless steel is a tough and long-lasting option.
Though steel fittings are usually more expensive than hydraulic connectors made from other materials, their reliability in a wide range of environments has made it the ideal choice in oil, gas, and offshore equipment, marine, chemical processing, food manufacturing, and a whole host of other industries.
Carbon Steel: Carbon steel is durable, strong, and has high heat resistance. An alloy of iron and carbon, and often alloyed with other metals to improve its strength, carbon steel has a temperature range of –54°C to 260°C.
A Trivalent Zinc external coating is used to enhance protection from salt and fertilizers in agricultural applications.
A lower-cost option, carbon steel is commonly used across arduous, high pressure, high such as agriculture, construction and heavy industry.
Brass: An alloy primarily of copper and zinc, brass has moderate strength and toughness. With a temperature range between –198° and 204° C, it also has good corrosion resistance with good ductility at high temperatures, though it’s not recommended for temperatures over 200° C as it softens and weakens. Only able to stand pressures to 3000 psi, most brass fitting applications are rated for lower pressures.
Aluminum: Deployed where a lightweight is critical – such as in aerospace, the military, and automotive industries – corrosion-resistant aluminium has a temperature range between –198°C to 204°C.
Untreated aluminum has low tensile strength and tends to be used for its corrosion resistance and lightweight in low-pressure applications. To improve strength and hardness it is alloyed with zinc, copper, silicon, and manganese for strength. Heat-treated aluminum alloy fittings can reach a pressure rating higher than brass of 4000 psi.
Technological Advances and Technical Advice
Typically, and sensibly, most industry verticals have tended to stick with the fittings and connector materials they’re always been familiar with. And why not? Who wants to stock every connector option, in every material, just in case?
When it comes to new designs and products through the introduction of innovative new design and new high performance, low-cost materials has got to be a good thing.
For advice on the hydraulic connectors and the hydraulic hoses and fittings right for your business, now and in the future, it’s best to speak with a proven and professional international couplings manufacturer.
