摘要： A carbon steel screw has one or more portions which have been selectively hardened by selective heat treatment and quenching. In one embodiment, an upper portion of the screw head is selectively hardened to prevent or reduce damage when torque is applied using a driving tool. In another embodiment, the screw tip is selectively hardened for more effective penetration into a substrate. Preferably, the selectively heated portions are selectively quenched to reduce or avoid distortion.

摘要： When a hot-rolled steel strip 1 is rolled at a large rolling reduction by a cold-rolling mill 4, cracking and interlayer peeling occur in those mill-scales which can not keep up with the elongation of base steel so as to weaken the adhesiveness of the mill-scales to the base steel. When such a steel strip is then brushed, the threads of the brush penetrate into the cracks formed in the scale layer, whereby the mill-scales are removed from the steel strip. The rolling reduction R (%) is set to satisfy the formula of t×R≧150 in relation with the thickness t (&mgr;m) of the mill-scales. The mill-scales weakened in adhesiveness by the heavy-duty rolling are removed from the surface of the steep strip 1 by brush rolls 5 provided in the pass of the steel strip 1 between the cold-rolling mill 4 and the bridle rolls 5. Water or a water-soluble rolling oil having a large friction coefficient is preferably supplied to the roll bites between work rolls of the cold-rolling mill 4 and the steel strip 1 during the heavy-duty rolling. Since the steel strip 1 is given required properties by the heavy-duty rolling in advance of pickling 8, it is used as a cold-rolled steel strip having the required properties simply by heat treatment or slight cold-rolling after pickling.
摘要翻译：当通过冷轧机4以大的轧制压下轧制热轧钢带1时，在不能跟上基钢的伸长率的那些轧机中发生裂纹和层间剥离，从而削弱粘合性的轧机尺寸与基础钢。当这样的钢带被刷洗时，刷子的螺纹渗透到形成在刻度层中的裂缝中，从而从钢带上去除轧机。压下率R（％）设定为满足关于轧机厚度t（mum）的txR> = 150的公式。通过设置在冷轧机4和绷带辊5之间的钢带1的通道中的刷辊5，从陡坡1的表面除去重型轧制中的粘合性减小的轧制尺寸。水或摩擦系数大的水溶性轧制油优选在重型轧制期间供给到冷轧机4的工作辊与钢带1之间的轧辊。由于钢带1在酸洗8之前通过重型轧制被赋予所需的性能，所以通过热处理或酸洗后的轻微冷轧将其用作具有所需性能的冷轧钢带。

摘要： The invention provides a method for the continuous manufacture of ferritic stainless steel bands suitable for use in environments with frequent changes in temperature. It has been found preferable to have such band longitudinally displaced through a coating chamber wherein the band is provided with a coating of aluminum that is deposited thereon by means of physical vapor deposition technology during a time period sufficient so that aluminum becomes evenly distributed in the ferrite, after which a homogenization occurs at 950-1150° C.

摘要： A method for heat-treating a component of steel or cast iron, particularly a through hardening bearing steel component, involves heating the component to the austenitization temperature and holding the component at the austenitization temperature to achieve austenitization, rapidly quenching the component to approximately the martensite starting point (MS temperature) and holding the component at the bainite transformation temperature until partial bainite transformation occurs. After partial bainite transformation, the component is cooled down to and briefly held at room temperature, followed by short-cycle tempering.
