Knocking wrench

Use of tapping wrench:

The impact wrench is suitable for industries such as petroleum,chemical,metallurgical,power generation,refining,shipbuilding,and petrochemicals.It is a tool used in equipment installation,installation,and maintenance work.The impact wrench is divided into two types:metric and imperial.

Manufacturing standards for impact wrenches:

GB/T4392-1995 is a common style of solid wrench,with a striking end at the end and a fixed size opening at one end for turning nuts or bolts.

Material of the impact wrench:

The impact wrench is made of 45#medium carbon steel or 40Cr alloy steel through integral forging and processing.

Product specifications for impact wrench:

Specifications:17mm,19mm,22mm,24mm,27mm,30mm,32mm,36mm,41mm,46mm,50mm,55mm,60mm,65mm,70mm,75mm,80mm,85mm.

The process of striking a solid wrench:

After forming the impact wrench,it undergoes high-temperature blueing treatment.In a high content solution of sodium hydroxide and sodium nitrite,at a temperature above 140 degrees,a dense oxide film(Fe2O3 and Fe3O4)is formed on the surface of steel parts.Different steels have different color differences,which are independent of roughness;The blue film does not turn blue,so it needs to be treated with anti rust oil after turning blue.Other surface treatments can also be carried out according to customer requirements.

After processing,the tensile strength of the impact wrench made of beryllium bronze material can reach 35 degrees or more,and this material is a product that is both anti magnetic.Aluminum bronze alloy products can reach temperatures above 25 degrees,and can meet the different needs of customers for impact wrench products.The impact wrench is produced using aluminum bronze alloy and beryllium bronze alloy as raw materials.It is processed through multiple processes and has various surface treatments for customers to choose from.The surface treatment of tool products includes natural color and electrostatic spraying.
