Website Description
About the project
Kataltim website. ru positions itself as a reference book for designers. This is not just an information portal, but rather a tool for engineers and technologists who need accurate data for calculations and design. The main page immediately catches your eye with an abundance of links to technical sections, which indicates the applied nature of the resource.
Here you can find materials on metals, their properties and standards. The project is clearly tailored for those who work with steel, aluminum alloys or calculate heating elements. The information is presented dryly, without unnecessary words, only numbers, brands and GOSTs.
Main directions
The site’s content can be divided into several clear blocks, each of which solves its own problem:
- Materials science and mechanics. A huge list of steel grades (from St2 to 35ХМ) and aluminum alloys (AD1, D16T, V92 and others). For each group, mechanical properties and permissible stresses are indicated. There is even a section on elastic moduli and Poisson's ratios.
- Tolerances and fits. This is perhaps the most voluminous part. Here we examine the types of tolerances, tolerance fields for shafts and holes, hole and shaft systems. Tables of maximum deviations for different qualifications are given - from 4 to 17. Transitional fits with clearance and interference are highlighted separately.
- Structural elements. Dimensions of runs, undercuts, chamfers for metric and trapezoidal threads. Placement of holes for bolts in channels and I-beams in accordance with GOST 8240. Bending radii of pipes (water and gas, copper) and sheet material.
- Heat engineering and electric furnaces. Data on the maximum operating temperatures of heating elements, resistivity of alloys, thermal conductivity of corundum and mullite materials. There is information about products made from mineral wool and fiberglass of different densities.
- Online payments. Tools are available on the site for calculating beams of constant cross-section, geometric characteristics of torsional stiffness and permissible rotor imbalance.
Features of the site
The main feature of the resource is its utility. There are no longreads or marketing texts here. For reference only. For example, you can find specific maximum deviations for the axes of holes in a system of rectangular or polar coordinates, which is critical when assembling complex mechanisms.
It is interesting that the section on refractories is quite detailed: the breakdown is not just by type, but by specific compositions such as mullite-silica fibrous materials or ceramic fiber mats with temperatures up to 1430 C. This suggests that the audience of the site is highly specialized specialists working with high temperatures.
The menu structure on the main page looks like a classic catalog: Materials, Surface roughness, Calculations. Everything is logical and understandable to an engineer who is used to searching for data quickly.
Contact information
The site has the ability to ask a question via chat. This is the only direct communication channel listed in the navigation. There are no other contacts (phone numbers, addresses) in the provided texts.
FAQ
FAQ
What steel grades are in the directory?
The materials section lists carbon steels (St2St6, 0850), alloyed (40Kh, 30KhGT, 18KhGT) and cast (20L5OL). There is also data on aluminum alloys of the AD, AMg, D16 and others series.
Are there tolerance tables for bearings?
Yes, there is a section about tolerance fields and technical requirements for the seating surfaces of shafts and housings for rolling bearings in accordance with GOST 3325-85.
Is it possible to calculate the rotor imbalance online?
Judging by the menu structure, the website provides calculation of the permissible imbalance of the rotor assembly, as well as calculation of beams and torsional stiffness characteristics.
What thermal insulation materials are described?
Data on the thermal conductivity of products made of mineral wool, fiberglass and ceramic fiber mats is provided, indicating density and operating temperatures.
