High Tensile Steel Grade 8.8, 10.9 Fasteners Manufacturer, Supplier In Mumbai India

Alpha Overseas is a leading manufacturer of Carbon Steel Gr 8.8/ 10.9 Fasteners in Mumbai, India.

The Grade 10.9 standard applies to carbon steel bolts and studs with diameters ranging from M-6 to M-64. To obtain the needed qualities of grade 10.9, we use high carbon steel and high alloy steel raw materials. This standard has three common grades, 8.8, 10.9, and 12.9, which reflect material hardness strength and their corresponding mechanical qualities. Medium carbon steel that has been tempered. Class 8.8 is toughened but not as powerful as class 10.9. It is often applicable in automotive applications.
