Product Name : Steel pipe make the world go round

+tulejowe +gwintowane

Mechanical and chemical properties of steel grades, as well as their possible delivery conditions, are according to norm of
feedstock tubes subjected to chroming process.
Feedstock tubes are manufactured by cold drawing process, which provides needed dimensional precision, while different
delivery conditions are foreseen to help reaching various levels of mechanical properties, according to specific needs.
Our standard product is in steel grade E355+SR, always ready-on-stock. Thanks to “stress relieved” delivery condition it offers a
good compromise of the mechanical properties and the rigidity needed for obtainment of a shaft, reaching in the meanwhile
impact properties of a minimum average value of 27 Joule at -20°C*.
Although not alway noticed, they are everywhere: pipes. Steel pipe is used in many varied constructions: football
stadiums, cilinders, roller-coasters, ships, buildings, cranes, cars, etc. Van Leeuwen Buizen is an international
supplier of steel pipe, hollow sections, fittings, flanges and valves - all quality products made by respected
manufacturers and suppliers. Each product has a wide range of applications

Surface Treatment Bar: Origin Black, Origin Annealing bright, Turned, Peeled, Grinded

Heat Treatment/ Anealing
1) Forging
Preheat the steel carefully, then raise the temperature to 1150-1200°C for forging. Do not forge below 850°C.
2)Annealing
Heat the AISI 4140 slowly to 800-850°C and allow enough time for the steel to be thoroughly heated. Cool slowly in the furnace to 480°C followed by air cooling.
3)Stress Relieving
When parts are heavily machined, ground or otherwise subject to cold work, stress relieving will be beneficial prior to hardening.
4)Hardening
AISI 4140 steel is usually supplied ready heat treated to 18-22HRC. If further heat treatment is required annealed AISI 4140 should be heated slowly to 840-875°C and after adequate soaking at this temperature quench in oil. Temper as soon as the tools reach room temperature.
5)Tempering
Heat the AISI 4140 carefully to a suitable temperature selected by reference to a tempering chart or table (usually between 550-700°C, soak at the temperature for 2 hours per 25mm of ruling section, then allow to cool in air. Tempering between 250-375°C is not advised as tempering within this range will seriously reduce the impact value.
