Grade 10.9 is a carbon steel alloy that contains a very low content of boron added in its chemical composition. Referred to as a high tensile steel grade, this alloy is treated with the use of quenching and tempering. Using these heat treatment practices brings an increase in its tensile and mechanical properties, making the Grade 10.9 Bolt suited to applications in the automobile sector. Although the alloy contains trace quantities of both sulfur and phosphorus in its alloy, as a type of carbon steel, the corrosion resistance properties range from zero to very little.
This is why the Grade 10.9 Screw is specifically used in applications that require high tensile strength. So if an application were to demand a moderate level of corrosion resistance properties with high tensile strength, it would be ideal to coat the Grade 10.9 Threaded Rod. Coating the surface of the fasteners is possible by using either zinc by galvanization or electroplating it with zinc. Another popular surface treatment is coating it with an anti-corrosion oil, which mildly improves the corrosion resistance of the fasteners. Though, zinc plating and galvanizing the Grade 10.9 Stainless Steel Bolt are the most common techniques of making the fasteners resistant to corrosion. With a moderate content of carbon in this steel alloy, the material is tempered to optimize its hardness. First, the alloy is quenched, which makes the High tensile Class 10.9 Bolt extremely hard. Quenching is followed by subsequent treatment with tempering, which also reduces the brittleness of the alloy, as a result of quenching. It is interesting to note that the metric HT Grade 10.9 Screw is similar to SAE grade 8 fasteners. Although this metric grade is slightly lower in terms of its tensile strength value.
