Automobile precision steel pipe refers to the delivery of the final product plastic deformation or the State of the final heat treatment. Generally do not undergo heat treatment delivery of hot rolled or cold rolled (rolling) or manufacturing States; after heat treatment heat treatment State of delivery, or according to the type of heat treatment are fire (Chang Hua), quenching and tempering, solution annealed State. When you place an order order status should be indicated in the contract. Test project as required by current standards and ensure compliance with standards requirements, referred to as the guarantee conditions. Guarantee conditions can be divided into: basic guarantee conditions (also known as the conditions). Regardless of whether the customer indicated in the contract. Must be carried out according to the standard of the examination, and to ensure that test results are consistent with standards. Such as chemical composition, mechanical properties, dimensions, surface quality and testing, such as pressure or collapsing or expanding process experiments are required conditions. The terms and requirements, in order, by both parties, signed a technical agreement and indicated in the contract.
