Q1: What makes stainless steel stainless?

A1: Stainless steel must contain at least 10.5 % chromium. It is this element that reacts with the oxygen in the air to form a complex chrome-oxide surface layer that is invisible but strong enough to prevent further oxygen from "staining" (rusting) the surface. Higher levels of chromium and the addition of other alloying elements such as nickel and molybdenum enhance this surface layer and improve the corrosion resistance of the stainless material.

Q2: Can stainless steel rust?

A2: Stainless does not "rust" as you think of regular steel rusting with a red oxide on the surface that flakes off. If you see red rust it is probably due to some iron particles that have contaminated the surface of the stainless steel and it is these iron particles that are rusting. Look at the source of the rusting and see if you can remove it from the surface.

Q:The total floor distribution along the wall surface 40x4 galvanized flat steel, flat paint is painted yellow mark or brush a straight chute
Fire retardant anti-corrosion coating, waterproof and anti-corrosion, and insulation effect is good, can be painted on any material, anti high temperature insulation shielding current through, corona discharge point phenomenon. Good insulation is the most basic and reliable means to ensure the safe operation of electrical equipment and lines, and to prevent the occurrence of electric shock accidents. As for what brush Road, this seems to have no mandatory requirements. Hope to adopt!
Q:Is the laying of a 40X4 flat steel for fire fighting metal trunking?
Without laying, the cable bridge, each section of the joint, there is a copper wire to prepare flat belt connected, it is bridge grounding jumper cable.
Q:Difference between cold drawn flat steel and flat steel
Flat, refers to the width 12-300mm, thickness 4-60mm, cross section is rectangular in shape and with a blunt edge of steel. Flat steel can be finished steel, or can be used as the blank of welded pipe and thin slab for laminated sheet rolling. Main application: flat steel is used as a material, used for making iron, tools and machinery parts, and used as frame structures and escalators for buildings.
Q:What is the weight calculation formula for galvanized flat steel and galvanized steel angles?
(1) grounding wire is generally made of 40mm * 4mm galvanized flat steel.(2) galvanized steel or angle steel for earthing body. The diameter of the steel pipe is 50mm, the wall thickness of the pipe is not less than 3.5mm, and the length is 2 to 3m. Angle iron shall be 50mm * 50mm * 5mm.(3) the top of the grounding body from the ground 0.5 ~ 0.8m, in order to avoid thawing soil, soil resistivity or steel angle as the root number of the ground around the body and decide, generally not less than two, each spacing is 3 ~ 5m(4) the distance between the grounding body and the building is over 1.5m, and the distance between the grounding rod and the independent lightning rod is greater than 3m.(5) the connection of grounding wire and earthing body shall be done by lap welding.
Q:How can copper cables and flat steel be welded together?
The copper cable is pressed into the nose. It is punched through the steel and screwed,The national standard atlas is connected with a total equipotential terminal box.
Q:What are the standards for the use of galvanized steel angles and flat steel for grounding?
The distance of the grounding body from the building is over 1.5m, and the distance from the grounding rod of the independent lightning conductor is greater than 3m.(5) the connection of grounding wire and earthing body shall be done by lap welding.
Q:The difference between use and performance of hot rolled flat steel and longitudinally cut flat steel is discussed
Hot rolled flat steel (hot rolled flat steel strip):Mostly produced by small factories, the raw material sources are disordered and the material can not be guaranteed. Therefore, the mechanical properties of hot-rolled flat steel are greatly different. Hardness, tensile strength, elongation, weldability are often unpredictable.
Q:-40x4 hot galvanized flat steel, a water 1m, what do you mean?
This is an auxiliary grounding electrode lead, if the main body foundation has reached the design resistance of less than 4 ohms, can not be auxiliary grounding electrode.
Q:Is medium plate steel flat?
Medium and heavy steel plate is mainly used in construction engineering, machinery manufacturing, container manufacturing, shipbuilding, bridge construction, etc.. Can also be used to manufacture all kinds of containers, furnace shell and plate, bridge and vehicle static steel, low alloy steel plate, ship plate, boiler plate, pressure vessel steel plate, embossed steel plate, steel plate for automobile frames, tractor parts and some welding components etc.. Through the plate uses: widely used in the manufacture of various containers, furnace shell and plate, bridge and vehicle static steel, low alloy steel plate, bridge plate, boiler plate, steel plate, a pressure vessel steel plate, embossed steel plate, steel plate for automobile frames, tractor parts and some welding component application.
Q:Galvanized steel flat welding occurs after the material itself crack.
Reheat cracking: when welding in the heat affected zone near the fusion County Office is heated to 1200 DEG C, the heat affected zone of grain boundary of vanadium and molybdenum and titanium carbide in austenite when welding; postweld heat treatment of re heating, the heating temperature in the range of 500 degrees to 700 degrees Celsius in the welding, there is a big the welding residual stress in the joints, stress exceeds the plastic heat affected zone near the fusion line of the metal, will produce crack;
