Abstract
The invention relates to a production method of 3/4 hard 301 precision stainless steel strip including the following steps that (1) the stainless steel strip is selected as the raw material; (2) the stainless steel strip is rolled and processed; (3) anneal to the strip is carried out; (4) further rolling is conducted; (5) the stainless steel strip is precisely trimmed; (6) the product is checked and packaged and stored in a warehouse. The invention not only improves the mechanic performance of the finished product but also eliminates the internal stress of the stainless steel owing to the preliminary rolling, thus improving the performance and quality of the finished product. In addition, the production method is simple with low cost.
Description
Technical field
The invention belongs to the manufacturing method of stainless steel band field, particularly relate to a kind of 301 precise stainless steel strip production methods.
Background technology
The stainless steel band product in use will carry out deep processings such as punching press, clod wash, and the deep process difference is also different to the mechanical property requirements of stainless steel band product.Usually, the stainless steel band product of stretched punch process is 3/4 hard attitude, and the mechanical property requirements of 301 materials, 3/4 hard attitude product is Hv=370～430.
In the prior art, stainless steel adds directly carry out finish rolling man-hour after first rolling processing, but can produce stress because first rolling back stainless steel is inner, influence the effect of finish rolling, dissimilar steel band Hv requires different prior aries to be difficult to satisfy requirement to the mechanical property of finished product simultaneously.
Summary of the invention
Technical problem to be solved by this invention provides a kind of 3/4 hard attitude 301 precise stainless steel strip production methods to solve the defective that is difficult to guarantee the finished product mechanical property in the prior art.
Technical scheme
The invention provides a kind of 3/4 hard attitude 301 precise stainless steel strip production methods, may further comprise the steps:
(1) adopting stainless steel band is raw material;
(2) rolling processing;
(3) annealing in process;
(4) finish rolling;
(5) finishing is cleaned, and straightening cuts into the width specifications of requirement then;
(6) check, packing warehouse-in.
Annealing temperature is 1060 ℃～1070 ℃ in the described step 3, and 15 minutes～25 minutes, decomposed ammonia protection, cooling fast.
Cold rolling machining deformation rate 30%～33%, two passages in the described step 4 are rolling.
Beneficial effect
The present invention has carried out once annealing after first rolling, not only improved the mechanical property of end product, and has eliminated stainless steel because of the internal stress that breaking down produces, and has improved the performance quality of end product, and production method is simple simultaneously, and cost is low.
