Carbon S960QL hardness grade vs stainless steel

API 5CT Casing pipes S960QL hardness supplied by BBN is mostly used in well structure building. Good quality API 5CT casing pipe could ensure well structure stability, isolate water and sand from tube working area, so drilling, oil production and other operations can be taken with no contamination. We can provide S960QL hardness you conductor casing pipe, surface casing pipe, intermediate casing pipe, production casing pipe.

The company adheres to the "variety, quality and efficiency" road. We have established a technology center, a brand cultivation management system and a quality control system. Now the company has formed an independent innovation system integrating S960QL hardness production, learning, research and marketing. Our company has passed ISO9001 quality management system certification and ISO10012 measurement management system certification.

"Mirror" refers to the surface state of S960QL hardness stainless steel, which is usually 8K in the industry. The common mirror stainless steel on the market is divided into 6K, 8K and 10K, which are general polishing, 6K, 8K fine grinding and 10K super fine grinding effect. The same thickness generally has no big difference, 10K mirror is brighter; the thicker the thickness, the better the effect, and the higher the processing cost.

Although S960QL hardness, low carbon steel has excellent plasticity, toughness and processing technology, its strength is low and its corrosion resistance is not strong enough. On the basis of ordinary low carbon steel, the low alloy structural steel with high strength, high toughness, good weldability and corrosion resistance can be obtained by adding a small amount of alloy elements and the total amount is less than 3%. Manganese is the main additive element in this kind of steel, and its content is about 1% ~ 1.6%.

After the order is finished, our after-sales service center will send an email to make a feedback about our steel products' quality. We have phone service every three months to remind our customers of the possible problems and collect advices or suggestions in quality and service. Upon the collection of advices or suggestions, our after-sales service will quickly make technical solutions to wipe out the customer problem.
