Factors to Determine Static Strengths of Spot-weld

Considering an application for automotive body structure, variations in TSS and CTS for high-strength steel sheets are summarized with their dependence on sheet strength and thickness, steel chemistry, and coating. In case of so-called button fracture, both of TSS and CTS seem to be proportional to the strength and thickness of sheets and nugget diameter, but the proportional constant is

Thus, when applying ultra-high strength steel sheets

Development of High Strength Steel Sheets and Practical

Feb 01, 1995 · The practical application of high strength steel sheets to autobody parts has been increased year by year in order to promote weight reduction and ensuring safety. New types of high strength steels with good formability have been developed and the average weight ratio of high strength steel in a whitebody is over 20 % in Japan. Evaluation of Hydrogen Embrittlement for High Strength Steel sheets for automobiles are usually formed into various parts by cold working. Therefore, plastic strain introduced by the cold working must be considered as a factor affecting the hydrogen embrittlement in addition to the applied stress and the content of diffusible hydrogen entered into steels, which are considered as factors in the studies of high strength steel bolts.

HSLA Steel Sheet. Low alloy steel (HSLA) is referred to alloy elements less than 3.5% of the total. Relative to carbon steel, low alloy steel, on the basis of carbon steel in order to improve one or more performances of steel is added one or several alloy steel elements. The alloy is more than

High Strength Steel Research Papers - Academia.edu

ABSTRACT Precipitation and texture formation in two cold rolled and batch-annealed interstitial-free high strength steels have been studied. TiN, Fe(Ti + Nb)P and TiC were the main precipitates observed. A perceptibly higher population of Fe(Ti + Nb)P precipitates in the steel containing a higher amount of P is considered to be primarily High Strength Steels for Automobile Use and the Role of Categories of deformation mode in press forming of sheet steels. High strength steels for different components of auto-bodies will be discussed here. High Strength Steels for Chassis Parts Corrosion and fatigue resistances as well as a sufficient rigidity are required to chassis parts, and as hot rolled steel sheets are, in general, applied.

High-Strength Steel Sheets for Automobile Body Panels

and crash-worthiness requirements, the steel industry has developed a large variety of steels and processes for producing high-strength cold-rolled steel sheets having yield strengths ranging from 40 to 160 ksi (275 to 1100 MPa)(l-4)*. The possible applications for high-strength cold-rolled steel sheets can be divided into two general categories : PREDICTION OF FORMING LIMIT OF HIGH-STRENGTH Materials used in this study are a mild steel sheet (A) and two types of high-strength steel sheets (B and C) with a thickness of 1.2 mm. They are eed as materials A, B and C, respectively, in the later description. The uniaxial tension tests were carried out in the directions of 0, 45 and 90° to rolling. Fig. 1

Physical Metallurgy of Modern High Strength Steel Sheets

A useful means of doing this is the application of high strength steel sheets to automobile bodies. The inferior formability of high strength steel sheets in comparison with that of mild steel sheets, however, hinders their broad application. But in recent years, many high strength steel sheets with good formability have been developed using Prevention of delayed cracking of punched 1.5 GPa ultra Aug 02, 2020 · For the weight reduction and passenger safety of automobiles, the use of ultra-high strength steel sheets having a tensile strength above 1 GPa for body-in-white parts rapidly increases [].The strength of the ultra-high strength steel sheets used for cold stamping attains 1.5 GPa at present [], and this strength is the same level as hot-stamped parts made of quenchable 22MnB5 steel sheets [].

Review Physical Metallurgy of Modern High Strength

For high strength steel sheets with a tensile strength level of less than 450MPa mainly used for outer and inner pan-els, high stretch formability and good deep drawability are generally key requirements. On the other hand, good elon-gation-angeability is often required for high strength steel sheets with a strength level between 450 and 1000MPa Slight clearance punching of ultra-high strength steel Feb 01, 2013 · Highlights Ultra-high strength steel sheets were punched with a punch having a small round edge. Slight clearance was used to improve the quality of the sheared edge. No crack from the edge of the punch was generated by relaxing deformation. Shiny burnished surface of the sheared edge increased. Both small round edge and slight clearance are indispensable.
