stainless steel commercial flat washers are used under bolt heads or nuts to increase the bearing surface area, or to offer protection so that the nut or bolt can be rotated without distortion of the bearing surface. Flat washers are also used to give tightness to a joint, to prevent leakage, and especially to distribute pressure under the head of a bolt or nut. Dimensional specifications are governed by ASME B18.21.1. Commercial flat washers generally have a larger outer diameter than SAE (Society of Automotive Engineers) flat washers, and can be utilized in nearly any application. stainless steel fasteners are commonly used in applications that require general atmospheric corrosion resist ance, such as chemical and food processing equipment. Stainless steel has a higher corrosion resistance than carbon steel.

Qitai County is rich in granite resources, mainly distributed in the Sujiquan area of ​​Beitashan Mountain. It has large reserves, good stone quality, small color difference, shallow mineral deposits and easy mining. It is mainly used for building exterior wall decoration and is a rare yellow granite mine in the world. The rock has a hard texture and a small grain structure, forming yellow, white, blue, white and black intersecting irregular patterns, luxurious and elegant, beautiful and generous, and is highly praised by domestic stone enterprises.
In recent years, our county has deeply implemented the strategy of transforming superior resources proposed by the autonomous region, relying on abundant stone resources, continuously increasing investment and efforts, and vigorously developing the building materials industry. An autonomous regional-level industrial park was established, and a stone industrial park of 4.4 square kilometers was planned and constructed, which realized the “eight connections and one leveling†of roads, power supply, water supply, communication and venues. There are 78 enterprises built in the industrial park. In 2012, the production of plates was 10.65 million square meters, an increase of 61% compared with 2011; the industrial output value was 1.27 billion yuan, a year-on-year increase of 59%; the industrial added value was 445 million yuan, a year-on-year increase of 63%, accounting for the county. The industrial added value is 25.9%; the contribution rate to the county's industrial growth is 28%, which drives the industrial economic growth by 17%; the county's plate production accounts for more than 50% of Xinjiang's stone production, accounting for more than 3% of the country. The products have been exported to more than 20 provinces such as Beijing, Shanghai and Zhejiang, and more than 10 countries including Kazakhstan. The three brands of Kalamailijin, Kalamaili Silver and Gobi Sapphire, which were built in our county, were rated as “National Famous Stone Grades†by China Stone Association, and won the stone number of National Building Materials. Kalamaili has become China's top ten best-selling domestic granite brand.
In the future, we will rely on the China Stone (Granite) Industrial Base in Qitai County to seize development opportunities and implement the strategy of large industry and large park in accordance with the requirements of “sustainable resource development and sustainable environmental protectionâ€, focusing on project construction. We will focus on plate production, park construction, mining area management, safe production, industrial transformation, etc., accelerate the development of the stone industry, promote new breakthroughs in the development of the stone industry in our county, and take a new step to make the economic development of Qitai County leapfrog. New contributions.
