Quenched and tempered steel - Import export

are bolts hot forged from all common materials including stainless, acid resistant and heatproof (inductive hardening, case hardening, quenched and tempered) steel. Diameter range of M 12 - M 80 with lengths reaching up to 800 mm. Tailored manufacturing according to specific standards, drawings and samples.

HT spur gear bevel gear spiral gear Steel quench and tempered, bronze etc. Custom made according drawing With our specialized expertise in custom gear, gear shaft, castings parts, forging parts, machined parts, welding parts for almost three decades, we can assist you on your industrial development. Our company (Huan-Tai) is rooted in China since mid-90’s. As one of the early runners, we bring value to the table through our capabilities in engineering, quality control and schedule management that meet the high expectations of overseas customers in stability, consistency and predictability. We are proud of our core competence in industry leading production processes, spectrometer analysis, critical NDT and tight tolerance machining.

This material group stands for breaking strength, service life and wear resistance. Due to these properties, quenched and tempered steel is always used where high strength, yield strength and high toughness are required for highly stressed machine parts. C 22 E, C35 E, C 45 E/➔ according to DIN EN 10132 - 3 Depending on the customer's requirements, we supply treatment states from soft annealed to high cold solidified.

PT screws for thermoplastics: Thread rolling screws for direct screwing into plastics, Thread 30° or 60° KTG screws for thermoplastics: Single-start or double-start thread (high, low) Thread rolling screws are extruded for larger batch sizes and turned for small batch sizes (Turned parts for direct screwing) High tensile and highly stressable connection of thermoplastics with considerably longer life endurance Thread rolling without chips and loss of material Minimum radial tension, large thread coverage Process-reliable due to torsion strength Shorter and slimmer screws are possible. Materials: Steel, case-hardened Quenched and tempered steel 1.5523 tempered to 1000 +200 N/mm², high-grade steel 1.4567, other materials on request Length: 3 – 160 mm (at lengths from 60 mm only partial thread lengths 4 x d are possible) Thread diameter: 1.6 – 10 mm Special dimensions on request Batch sizes: Standard ex-stores Special screws from 30,000 pieces

We supply the European and international market with cold heading wire / cold extruding steel in sizes ranging from 1.5 mm to 42 mm Production is based at the Hamm and Iserlohn sites, focussing on the following products: Cold heading wire / cold extruding steel Tempering steel Quenched and tempered steels / AFP steels Prehardened steels

The AL-ROCK is a laser hardening system for surface hardening with a self-propelled caterpillar track. The laser can be brought directly to the workpiece. Time-consuming removal of the components to be hardened can often be avoided. The robot arm easily reaches the hard-to-reach places on the workpiece. All common metals can be hardened, e.g. Quenched and tempered steels, cold work steels and cast steel or gray cast iron. The material must have at least 80% pearlite. The degrees of hardness that can be achieved are identical to those of conventional hardening processes. In free 3D movements, the laser beam precisely follows even the most demanding three-dimensional workpiece contours, for example on tracks along closing edges. Pimples, scar structures. Simple points are also not a problem. Only the free access of the laser beam to the surface to be hardened is required. And the AL-ROCK can do even more - on request, the laser robot can also be used for laser welding.
