FAQ：
Q1: How do we guarantee the quality of our products?
A1: We have established an advanced quality management system which conducts strict quality tests at every step, from raw materials to the final product. At the same time, we provide extensive follow-up service assurances as required.
Q2: What makes stainless steel stainless?
A2: 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.
- Q:How do you calculate the deflection of a steel round bar?
- To calculate the deflection of a steel round bar, you need to consider various factors such as the bar's length, diameter, and the applied load. The deflection of a bar refers to the amount it bends or flexes under a specific load. The deflection can be determined using the formula for beam deflection, which is derived from Euler-Bernoulli beam theory. The formula is as follows: δ = (F * L^3) / (48 * E * I) Where: - δ represents deflection - F is the applied load - L is the length of the bar - E is the modulus of elasticity of the steel material - I is the moment of inertia of the round bar To calculate the moment of inertia (I) for a round bar, you can use the formula: I = (π * D^4) / 64 Where: - I is the moment of inertia - D is the diameter of the round bar By substituting the values into the formula, you can calculate the deflection of the steel round bar under the given load. It is important to note that these calculations assume the bar is perfectly elastic and obeys the principles of linear elasticity.
