If you mean what HB stands for, it's an indicator for the hardness (H) or softness (B) of the graphite and clay used.
However, the B is for blackness so HB is like average/medium grade so the full form would be Hard Black, Hard and Black, or Hard Blackness.
If you check out pencils like 3H, you'll notice that the tone when writing or drawing is light compared to an HB. Conversely, a 3B pencil will give you a darker tone.

AnswerThere isn't any difference, HB or H B always stands for 'hard black'. Softer pencils have 2B, 4B, 5B etc, where the higher the number means the softer (and therefore less black) the pencil. Answerone is the shade of a pencil the other is just two letters spaced outWiki User
∙ 16y agoIn pencil classification, H stands for hardness and B for blackness. HB therefore refers to a pencil that is "Hard black"; one degree of hardness and one degree of blackness. The scale runs from 9H (very hard) to 9B (very soft/black) with HB as the central grading. This scale also includes "F" referring to "Fine Point".

∙ 10y agoH = Hardness, and B = Black. Pencils are graded from 9H to 9B. HB is the 'middle' rating. Going away from HB, they would be graded 2H & 3H, or 2B & 3B etc.

the mechanical pencil will write better because it has a skinnier lead, so the pencil doesn't go flat if you write too much on one side. the lead also still graphite, but has special substances in it to help you write better. Still, if your pencil is certified HB#2, it can be used on Scantron Genuine Forms and State tests.

I don't quite understand what you mean by HB-2 pencil but if you mean HB pencil / #2 Pencil it is not the softest pencil. Pencils scale from 9H to 9B, (HB in the middle) and 9B would the softest and darkest pencil there.
HB stands for "hard black" and is a designation used to indicate the hardness and darkness of the graphite core in a pencil. The HB pencil is commonly used for general writing and drawing purposes.
HB 2 pencil has a slightly softer lead than a regular HB pencil, which gives it darker markings. The "2" in HB 2 stands for the American grading system, while the regular HB is based on the European grading system. Both are commonly used for general writing and drawing.
No, HB-2 pencils do not have the softest lead. The hardness of the lead in a pencil is determined by the graphite grading scale. HB pencils have a medium hardness, while softer leads like 2B or 4B will produce darker and smoother lines.
