FAQ

1. Q: What's the MOQ?

A: Our MOQ is 25mt.

2. Q: What's the delivery time?

A: It will take about 30 days after TT or L/C.

3. Q: What is the payment terms?

A: T/T, L/C at sight

4. Q: How does your factory carry out quality control?

A: We attach great importance to quality control.Every part of our products has its own QC.

5. Q: What certificate do you have?

A: We have SGS, ISO9001 etc. Also we can apply any certificate if you need if the qty is OK.

Q: if steel is heated from room temperature (20c) to (500c) what would be the change in density?coefficient for linear expansion of steel 12x10^-6 k density of steel 7800 kg: First you have to convert the coefficient of linear expansion to a coefficient of volumetric expansion. Multiply the coefficient of linear expansion by 3: Coefficient of expansion of steel,β:12E-6/°K x 3 = 36E-6/°K Difference in temperature: 480°K ΔV = VoβΔT ΔV = Vo x (0.000036) x 480 ΔV = 1m? x 0.017 ΔV = 0.017m? Originally, the steel was at 7800 kg/m? Now, the steel was at 7800 kg/ 1.017m?, or 7670 kg/m? Change in density = 7670 - 7800 = -130kg/m?

Q: So what's harder gold or steel: steel. gold is pretty soft.

Q: How are steel coils used in the production of building facades?: Steel coils are commonly used in the production of building facades as they provide strength, durability, and versatility. These coils are typically processed into flat sheets or panels and then cut, shaped, and attached to the framework of the facade. The steel coils can be coated with various finishes or paints to enhance their aesthetic appeal and protect against corrosion. Overall, steel coils play a crucial role in constructing robust and visually appealing building facades.

Q: What are the common methods of joining steel coils?: The common methods of joining steel coils include welding, mechanical fastening (such as bolts or screws), and adhesive bonding.

Q: And by how much? I'm pretty sure that sterling silver is stronger, but I'm wondering if I could still use a metal stamp to stamp into something that's stainless steel - if it would be soft enough?: No way steel is by far stronger. Tensile strength of Sterling silver 207 MPa Tensile strength of Stainless Steel 515 MPa

Q: Is there any noticable or perceived difference between smoking out of a pipe with a brass screen and a stainless steel screen?: Stainless Steel Pipe Screens

Q: What are the common tests performed on steel coils for quality assurance?: The common tests performed on steel coils for quality assurance include visual inspection, dimensional analysis, tensile strength testing, hardness testing, and surface quality assessment.

Q: Can steel coils be stamped?: Yes, steel coils can be stamped.

Q: Is there alloys in low carbon steel or non: Steel is an alloy. An alloy is a mixture of metals melted together, a solid solution. There are many recipes for steel depending on what the use is. Steel is an alloy of iron and another metal .Low carbon steel has less than 0.3% carbon, carbon steel is 0.3 to 0.6% carbon Low carbon steels generally contain less than 0.25% carbon and cannot be strengthened by heat-treating (strengthening can only be accomplished through cold working). The low carbon material is relatively soft and weak, but has outstanding ductility and toughness. In addition, it is machineable, weld-able, and is relatively inexpensive to produce. Carbon steel, also called plain carbon steel, is steel where the main alloying constituent is carbon. The American Iron and Steel Institute (AISI) defines carbon steel as: Steel is considered to be carbon steel when no minimum content is specified or required for chromium, cobalt, columbium, molybdenum, nickel, titanium, tungsten, vanadium or zirconium, or any other element to be added to obtain a desired alloying effect; when the specified minimum for copper does not exceed 0.40 percent; or when the maximum content specified for any of the following elements does not exceed the percentages noted: manganese 1.65, silicon 0.60, copper 0.60.
