Q
What Is Stainless Steel?
AStainless steel is an alloy of Iron with a minimum of 10.5% Chromium. Chromium produces a thin layer of oxide on the surface of the steel known as the 'passive layer'. This prevents any further corrosion of the surface. Increasing the amount of Chromium gives an increased resistance to corrosion.
Stainless steel also contains varying amounts of Carbon, Silicon and Manganese. Other elements such as Nickel and Molybdenum may be added to impart other useful properties such as enhanced formability and increased corrosion resistance. -
Q
What makes cadmium a desirable plating material for fasteners?
AWhile there have been many issues involving the environment, safety, and health, the inherent lubricity characteristic of this plating material has never been completely duplicated over a full range of applications. For instance, in salt water, a cadmium coating forms a protective cadmium chloride surface layer which is not sacrificial.

Q
What are the fasteners general guidelines for COATING THICKNESSES ?
ATo ensure thread assemble ability of mating fasteners, the specified thread fit allowance in the inch series, divided by 6, provides the maximum coating thickness.

Q
Why use coating and plating in fasteners?
AUsually coatings and platings are less expensive than employing an upgrade from a basic carbon steel to a premium material such as stainless steel. Coatings or platings may help to improve appearance, control torque tension, minimize thread seizure, and may serve as product identifiers.

Q
How are the 3D pressure components tested?
AThe most accurate examination method is computed tomography (CT-scan).
Here not only the dimensional compliance can be checked, but also for example.
The density of the components.By coloring the test, deviation can be quickly recognized.
This method makes particular sense in components with internal structures. -
Q
Is metal 3D printing fundamentally more expensive than machining?
AYes and no. If one chooses a very "simply knitted" component, such as simple angles or brackets for example, you will definitely get away with the regular machining more cheaply.However, if one chooses a component, which is particularly emphasized by its complexity or bionic component geometry, one can achieve great savings.

Q
How much should you charge for a 3D print?
AAlmost every maker gets stuck on this question: How much to charge? There are a lot of factors that need to be included in the price. Like the cost of the material used, the energy used, the time that the 3D Printer will take to printer the model.

Q
How long does a 3D print take?
AThat depends on several factors:
1,The size of your model;
2,The material you are using;
3,The layer height (smaller layers mean more layers to print);
4,The complexity of your model;
5,Whether the object needs supports. -
