Low alloy seamless rectangular pipe

Low alloy seamless rectangular mild steel pipe is seamless low alloy pipe extrusion.

The plastic

Plastic refers to metal materials under loading, the plastic deformation (permanent deformation) and does not destroy the ability.

hardness

The pointer to the hardness was measured degree of hard and soft metal materials. At present in the production of measuring hardness is pressed into the hardness of the most commonly used method, it is to use a certain geometry head to a certain load tested down into the surface of the metal material, according to the degree by the determination of the hardness value. The commonly used methods are brinell hardness (HB) and rockwell hardness (HRA, HRB, HRC) and vickers hardness (HV) and other methods.

fatigue

Discussed earlier strength, plasticity and hardness are Pointers on the mechanical properties of the metal under the action of static load. In fact, many machine parts are working under cyclic load, under the condition of the parts will get tired.

Impact toughness

With great speed of load acting on the object known as impact load, metal under impact load is low alloy rectangular call the ability to resist impact toughness.

The intensity of

Intensity refers to the metal material under static loading resistance destruction (excess plastic deformation or fracture) performance. As a result of the action of load way has the form such as tensile, compression, bending, shear, so the strength also divided into tensile strength, compressive strength, bending strength, shear strength and so on. Always have a connection between various strength, more commonly in use in the strength of the tensile strength as the most basic pointer.

Square welded steel pipe is used often in industry.
