Effect of Processing Technology on Mechanical Properties of HRB500 High-Strength Steel Bar Threading
نویسندگان
چکیده
The processing quality of steel bar thread has a large influence on its performance. Using the traditional technology, it is difficult to meet requirements with diameter and high strength. A technical process for HRB500 high-strength processing, including face milling, rib stripping, chamfering, necking formation, rolling, was proposed. influences cutting parameters force surface in milling were analyzed by finite element method. For formation process, effect springback amount studied. main rolling calculated, extrusion pressure, speed, feed. Experiments uniaxial tensile processed threads carried out. results showed that depth largest force; second feed rate. spindle speed lowest during milling. After values maximum along X, Y, Z directions 0.05 mm, 0.06 0.98 respectively. finished met precision grade I joint. This study provides high-quality technology large-diameter threads.

The Effect of Controlled Thermo Mechanical Processing on the Properties of a High Strength Steel
In this paper, an ultra low carbon High Strength Low Alloy Grade Steel was subjected to a two-step forging process and this was followed by different post cooling methods. The highest strength was obtained at a faster cooling rate due to the highly dislocated acicular ferrite structure with the fine precipitation of microalloying carbides and carbonitrides. At a slow cooling rate, the strength ...

In this research the influence of Ti contents on the amounts of inclusions formation and mechanical properties of a high alloy high strength steel, C300, has been investigated. For this purpose several bars were casted under the same solidification conditions, but different amounts of Ti element. All the seven casted bars were homogenized at 1200°C for a period of 2 hours. Then, they were immed...
