Wear-resistant steel Material: BTW1 Size: 10-80 * 1000-2500 * 2000-8000 Standard: GB / T709-2006 chemical composition C: 0.90-1.20 Si: ≤0.40 Mn: 6.00-9.00 Cr: 0.30-3.00 V: 0.10 -2.00 Mo: 0.10-2.00 mechanical properties: σb: 650-800 σ0.2: 400-480 A%: ≥20 Z%: ≥20 AKv2: ≥50 HBW≤250 Features: EAF + vertical continuous casting process Production of steel with high purity, uniform texture, with excellent toughness and wear resistance of the manufacturing process: external electric → refining → casting → hot delivery → hot rolling → solution → finishing → product testing → factory applications : widely used in conveyor, mining crushing machinery, pipelines, construction vehicles and excavators and other mining coal and other delivery status: the use of water and tough handling state, black delivery, trimming can be delivered, but also flash can be delivered, please indicate in the contract delivery hardness: after toughening treatment water hardness steel microstructure ≤250HBW: austenite + dispersed carbide wear: impact wear test: 200N, 600N speed specimen 180 rev / min, at a sample of 200 revolutions / minute Shock amplitude and frequency: amplitude 2mm, frequency: 231 minutes test rotational speed: 90,000 turn strengthening mechanism: BTW series of wear-resistant steel at low impact loads, with strain-induced horse martensitic phase transformation characteristics. With the improvement of the impact load, strain-induced martensitic transformation increase the amount, which will be increased to strengthen the layer hardness, impact resistance and fatigue also increase the wear resistance. In the strain-induced martensite also accompanied by phase transformation plasticity and toughness change, dramatically reducing the fatigue crack growth rate welding characteristics: BTW series products have excellent welding performance, the choice of MIG (MIG) welding of Methods for automatic welding process is stable and reliable performance. BTW special welding consumables need to use or CHM18-8Mn wire welding preparation: no warm-up, clean-up welding groove, the correct selection of welding consumables, the correct selection of the shielding gas. Welding process: Welding heat input as possible ≤12kJ / cm, and strictly control interpass temperature (≤150 ℃), the use of multi-pass welding, passes between the timely adoption of a water cooled welding, thus ensuring weldability. After the welding process: after welding without heat treatment, it may be appropriate to eliminate the welding stress hammering testing results of welded joints: X-ray detection, according to GB / T3323-2005 (BI level qualified), found at the end excessive defects. Ultrasonic testing, based on GB11345-89 (BI level qualified), found at the end excessive defects. Ultrasonic phased array flaw detection, see the end of a consecutive defect, a small amount of point-like defects Benefit Description: BTW steel can withstand greater impact loads without breaking, crushing anti-spalling and anti-wear properties of alloy steel other than 2-fold. Can be widely used in heavy-duty scraper conveyor plate, dump truck bed boards, silo panels, pipes and other materials. Good processing properties and weldability BTW wear-resistant steel, without preheating before welding, after welding without heat treatment, which is currently at home and abroad are not available to other wear plate outstanding features. Description: BTW wear-resistant steel during use, strain-induced martensitic transformation through principle, when a layer of hardened material surface is worn away, exposing new surface will be the same since strengthened its surface enhancement factor up to 2.5 times, the reinforcing layer depth of less than 1 mm, can significantly improve the surface hardness to HRC50-65. Therefore, the product surface, "the more the more hard grind", while achieving continued regeneration wear layer. In the center there is no plastic deformation occurred, remained high impact toughness, thereby protecting even wear parts, such as using the scraper significantly reduces wear and tear on the blade and BTW steel ring chains.
