GB 8547-87 Titanium-Steel Composite Plate
Titanium-steel composite plates are pre-engineered rolled steel plates of a specific thickness and specified size. They are typically used in production machines and equipment as well as in structural and load-bearing components. These composite plates combine the strength of titanium and the ductility of steel while also providing excellent corrosion resistance and durability compared to other materials.
Titanium-steel composite plates are made of two separate components, a low-tensile steel core and a high-tensile titanium alloy sheet covering. The steel core is usually made of a low carbon-manganese steel with a thickness of 4 to 15 millimetres, which is dependant on the intended use of the plate. The titanium alloy sheet covering the steel core is usually made of low-alloyed high-tensile titanium and ranges from 0.5 to 4 millimetres in thickness. This combination allows for the excellent tensile strength of the titanium alloy to be transferred to the steel core, thus ensuring a sturdy structure with immense strength and flexibility.
When properly manufactured, titanium-steel composite plates possess excellent features. The plates have a maximum tensile strength of up to 2800 MPa and can withstand temperatures up to 600℃, allowing them to be used in high-temperature applications such as turbines. The plates also have excellent corrosion-resistance due to the titaniums protective properties, making them ideal for use in humid, corrosive environments. Furthermore, titanium-steel composite plates are lightweight, making them ideal for applications where weight is a factor.
Proper installation of titanium-steel composite plates is essential to ensure the maximum performance and durability of the plates. A special bonding layer must be applied to both the steel core and the titanium alloy sheet in order to ensure a secure and robust bond upon installation. The plates must also be cut or machined to the specific shape and size required and then welded into position. Fastening systems such as bolts and rivets may also be used to affix the plates.
Titanium-steel composite plates have several advantages and are ideal for use in a variety of structural and load-bearing applications and components. Their ability to withstand high temperatures, their superior strength and corrosion-resistance, and their lightweight design mean these composite plates can be utilised in a range of applications, including construction and engineering, automotive and aerospace, marine and oil and gas industry.
