What is the thickness of Sphc?

SPHC (steel pickled and hot-rolled coil)

The thickness of SPHC (steel pickled and hot-rolled coil) is determined by the application and intended use of the product. SPHC steels may range in thickness from a minimum of approximately 0.25 mm (10 mils) up to a maximum of approximately 7 mm (280 mils). SPHC (steel pickled and hot-rolled coil) is a hot-rolled steel sheet immediately produced after the pickling process. The pickling process consists of cleaning, water removal of residual metals, and immediate rolling of the product immediately after pickling. The SPHC designation stands for “Standardized Value for Hot-Rolled Steel Coils”.

SPHC (steel pickled and hot-rolled coil) is widely used in the automotive industry, household appliances, general machinery, building, and many other industries.

The mechanical properties of SPHC steels depend on the thickness of the sheet or coil. The sheets can be categorized as thin, medium and thick. The mechanical properties of thin sheet material is considerably less than that of thicker sheet material. The thin sheet material is prone to deformation and has relatively low tensile strength.

SPHC steels thicker than 1.6 mm (0.062 inches) are generally referred to as heavy plates. The heavy plates offer better impact resistance, hardness, and higher strength than thin sheets. However, they can be more susceptible to developing internal stresses due to thermal expansion and contraction which occurs during their manufacture.

It is important to note that the thickness of a piece of SPHC (steel pickled and hot-rolled coil) is not a deciding factor in identifying its grade. The grade is determined by the tensile strength, yield strength, and elongation of the material. Generally speaking, lower grades are thicker and have a lower tensile strength and yield strength than higher grades.

In addition to the thickness of the material, the characteristics of SPHC (steel pickled and hot-rolled coil) also depend on the application requirements. For instance, oiled sheets can be used in automotive industry applications where high corrosion resistance is required. However, if an application calls for higher tensile strength, a thicker gauge of SPHC steel is required.
