Output for the first nine months of the year climbed 6.1% to a record 699.42 million tons. China's steelmakers pushed production rates to record levels last month, underscoring a broadly bullish picture for mills in the world’s biggest market as prices rally again. Output of crude steel rose 7.5% on year to 80.85 million metric tons, according to the statistics bureau Friday. That means a daily rate of 2.695 million tons, beating the previous all-time high of 2.673 million tons posted in June. Output for the first nine months of the year climbed 6.1% to a record 699.42 million tons. China’s mills have boosted output to benefit from an unusually long period of high prices and healthier profits that shows few signs of ending. The price of rebar used in construction rallied this week to the highest this year, while iron ore prices have surged to a March high, ahead of winter production curbs to fight pollution that are likely to continue to support the nation’s steel markets....

The plastic injection moulding process produces large numbers of parts of high quality with great accuracy, very quickly. Plastic material in the form of granules is melted until soft enough to be injected under pressure to fill a mould. The result is that the shape is exactly copied. Once the plastic moulding has cooled sufficiently to harden the injection mould opens releasing the part. The whole injection moulding process then repeats. CLOSE MOULD CLAMPING – the moving and fixed platens of the injection moulding machine hold the mould tool together under pressure. INJECT MOLTEN PLASTIC INJECTION – the molten plastic that has been melted from pellet form in the barrel of the moulding machine is injected under pressure into the mould. HOLD MOULD CLOSED DWELLING – after the molten plastic has been injected into the mould, the pressure is applied to ensure all cavities are filled. COOLING – the plastic parts are then allowed to solidify in the mould. OPEN MOULD &...

AISI 4140 steel grade is a versatile steel grade. 4140 material is widely used in a lots of industrial fields. It is a chromium-molybdenum alloy steel. The chromium content provides good hardness penetration, and the molybdenum content ensures uniform hardness and high strength. ASTM 4140 chrome-molybdenum steel can be oil hardened to a relatively high level of hardness. The desirable properties of the AISI steel 4140 include superior toughness, good ductility and good wear resistance in the quenched and tempered condition. Here we list 15 common applications for 4140 steels material: 1.Shaft 2. Crankshaft 3.Bolt 4.Machinery Parts 5. Gear 6. Milling Spindle 7. Nut 8. Slide 9. Steel Collet 10.Steel Conveyor and Roll 11. Steel Coupling 12. Drill Collar 13. Steel Ejector 14. Steel Piston Rod 15. Steel Stub Except for the above 15 applications for steel g...

When selecting a metal for a specific project, one of the most important considerations – especially when it comes to structural applications – is tensile strength and impact strength. Knowing what these mechanical properties are and how to evaluate them is essential to selecting the correct metal for your project. What Is Tensile Strength? Tensile strength is a value that indicates a metal’s ability to resist deformation and failure when loads are applied that pull it apart (known as tensile loads). Tensile strength is typically quantified through units of pounds per square inch (PSI) or pascals (Pa). There are 3 different types of tensile strengths: Tensile yield strength Ultimate tensile strength Fracture tensile strength The yield strength is the strength a metal has before it begins to plastically deform. The ultimate tensile strength is the maximum tensile strength a metal has, and it typically is found after plastic deformation has begun to occur. The fracture te...
