Description

High-strength cold rolled steel strip
Technical field
The present invention relates to cold rolled strip field, particularly relate to a kind of high-strength cold rolled steel strip.
Background technology
Stainless steel is common steel alloy, by metallographic structure classification, generally can be divided into: ferritic stainless steel, austenitic stainless steel, Martensite Stainless Steel and duplex stainless steel (ferritic-austenitic stainless steel).Produce the microstructure of Cr17 type ferrite stainless strip steel at present both at home and abroad based on ferrite, and add corrosion resisting property and the raising intensity that a small amount of trace alloying element titanium, niobium etc. improve steel, some steel grades also add molybdenum, because molybdenum valency goes up in recent years, add molybdenum and the cost of steel can be made to increase.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of high-strength cold rolled steel strip, can improve the intensity of cold rolled strip, reduces manufacturing cost, meets various user demand.
